Introduction

With our emphasis on Indoor Air Quality, comfort

cooling and dehumidification, we offer products

that allow you to improve the quality of your

indoor environment whilst reducing energy

consumption through efficient air treatment.

Indoor Air Quality is a vital factor affecting the

health of building occupants. With increasingly

long working hours, antiquated buildings and an

over-reliance on air-conditioning, occupants are

becoming more and more susceptible to

symptoms such as fatigue and headaches.

Enclosed spaces with little exposure to outside

air only increase the problems and illnesses

related to unhealthy environments.

The achievement of good Indoor Air Quality

depends upon a variety of factors; design,

construction, commissioning, facilities

management and building maintenance.

While the above must all play a vital role, the

major contributor to indoor comfort in the region

is the proper treatment of outside air and its

introduction to the indoor environment at a

sufficient rate. Only if all these issues are properly

addressed will buildings comply with standards

of excellence in energy efficient design.

Indoor comfort relies heavily on the introduction

of outside air. As this air contains significant

amounts of both moisture and heat, its

treatment is responsible for immense rates of

energy consumption. Only by combining the

requirements of air quality and energy efficient

air treatment can indoor climates be properly

and efficiently maintained.

Reducing the Costs of the Dehumidification Process

Dehumidifier Heat Pipes

Heat pipes significantly improve the effectiveness of dehumidification systems. They can double the moisture extraction rate while

improving the quality of the air. And it’s all done at zero running cost.

Improved air conditioning

Regional climates suffer from high humidity

combined with high temperatures. This often

results in air conditioning units supplying humid

air or excessive energy being expended on

traditional methods of overcooling and reheating.

Wrap-around, dehumidifier heat pipe systems

are fitted around the main cooling coil in the

primary air handling unit, simultaneously reducing

the load on the cooling coil and the need for

reheat further downstream. This process

provides an improvement in air quality resulting

from the additional rate of moisture removal and

the capacity to treat higher rates of outside air.

It also reduces the energy burden at no

additional cost; a heat pipe is a completely

passive device and is driven only by the

temperature difference imposed by the cooling

coil.

By using a wrap-around heat pipe in the primary

air handling unit, operating costs can be reduced

by up to 30%. At the same time, the overall

capital expenditure is unlikely to change as the

cost of the heat pipe is offset by the reduced

capital expenditure on the lower capacity cooling

system and the reduction in reheat equipment.

Not only will the energy requirement of the HVAC

equipment be reduced, but the Indoor Air Quality

will be significantly improved and lead to happier,

healthier working and living spaces.

Heat pipe advantages

• Totally passive; no moving parts

• No direct energy input

• Up to twice as much moisture

extraction as conventional systems

• No need for reheat or desiccant

systems

• Easy drainage of condensation

• Long-lasting – at least the lifetime of

the air conditioning system

• Virtually maintenance-free

• Environmentally safe

Air changes in occupied buildings are necessary

to remove pollutants and to continually refresh

the atmosphere; the greater the rate of air

changes the healthier the building. As the

outside air is hot, high energy and carbon costs

are accrued in bringing the outside air down to

the space temperature.

Wherever air is mechanically supplied and

removed from a building there is the opportunity

to install an energy-saving heat pipe – many

building regulations actually demand that heat

recovery is used. The principle is simple – the

heat pipe uses the cool dirty air from the extract

air stream to condition the incoming hot fresh air

supply and precool it prior to it being further

treated. The effectiveness of this process can be

as high as 70% and the running costs are

virtually nil due to the passive nature of the heat

pipes and their low airside pressure drops.

Additional capital expenditure is extremely low,

particularly when compared to other products

such as thermal wheels and plate heat

exchangers.

Unlike other types of heat recovery device a

heat pipe can recover and recycle heat without

the fear of contamination from the dirty extract.

Combine this with the ability to treat the heat

pipe to withstand corrosive environments and

the range of applications is virtually limitless.

Typical applications for energy recovery heat

pipes include outside air units, swimming pools,

drying processes, spray booths, laundries,

kitchens and hospitals where zero

cross-contamination is vital.

Recover up to 70% of the Heat Energy from Extracted Air

Heat Pipes for Energy Recovery

Cool extract air is a powerful weapon in the drive towards energy efficiency in the

region. Extracting air directly from a building is wasteful as this cool extract air has a

great potential for absorbing the heat from the outside air which is being introduced.

Passing the extract and outside air streams through a heat pipe heat exchanger

allows for up to 70% of the sensible cooling of the outside air to be provided free.

These systems are specifically designed to

drastically improve the air quality in the building

or facility. SPC Sanuvox proprietary systems

make it possible to deliver high amounts of UV

energy to the air stream while increasing ‘dwell

time’ between the air and the UV purifier. In

other words, the contaminated air is exposed

to the UV energy for considerably longer than

with competing systems.

These systems are designed to bask stationary

objects (usually an A/C Coil) with UVC light,

preventing and destroying mold and other

microbial growth. Although very effective in

keeping stationary objects clean, UV lamps

shining on an object will have little effect on any

other Indoor Air Quality concerns beyond the

mold laden coil.

UV Coil Cleaners have little effect on the air in

the duct. By treating the air in the duct with UV

Air Purifiers the coil will also be kept clean as the

biological contaminants in the air are reduced.

Destroy Biological Contaminants in the Moving Air Stream

Ultraviolet - Air and Object Purification

SPC Sanuvox Ultraviolet Air Purifiers are quality, cost efficient products that address

Indoor Air Quality and Sick Buildings issues by neutralizing bacteria and viruses

through exposure to UV radiation.

These industrial and commercial purifier systems can be designed to neutralize up to

99.999% of biological and chemical contaminants that travel throughout the building,

such as mold, bacteria, viruses, spores, allergens, cigarette smoke, garbage and

sewer odours, VOCs, diesel fumes and thousand of other airbourne contaminants.

Controlled and Conditioned Ventilation for Residences

DERV - Dehumidifying Energy Recovery Ventilators

DERV units are intended for energy recovery

and dehumidification of outside air in individual

residences, offices or other areas where there

is no central air conditioning plant. Behaving as

a miniature outside air handling unit, their

compact size allows them to be installed within

ceiling spaces. Ducting to and from the units

allows treated ventilation air to be supplied

direct to all zones of the residence and dirty

extract air to be removed from its various

sources.

DERV units are completely self-contained and

consist of a supply air section side by side with

an extract air section. Both supply and extract

sections incorporate powerful centrifugal fans

capable of supporting external static pressure

of up to 150Pa. An energy recovery heat pipe

straddles the supply and extract sections

allowing the hot outside air to be precooled by

the cooler extract air.

Downstream of the energy recovery heat pipe

is a cooling coil with a dehumidifier heat pipe

wrapped around it. This section of the unit

further cools the air before it is thoroughly

dehumidified by the cooling coil. The final leg of

the heat pipe then reheats the air to a

comfortable supply temperature.

If a source of chilled water is available then the

DERV unit can be equipped with a chilled water

cooling coil. If this facility is not available then the

DERV unit can be supplied with a matched

condensing unit for external mounting and the

unit equipped with a DX evaporator coil

(DERVDX unit).

The ERV unit is a variant which incorporates

only the energy recovery heat pipe and

supply/extract fans within the unit case.

This provides the possibility of energy recovery

when it is not feasible to link the unit to a supply

of chilled water or to couple it to an external

condensing unit.

DERV units combine the benefits of dehumidifier heat pipes and energy recovery

heat pipes in a single, finished unit.

The units are of a single or double skin panel

construction and panels are easily removable

for inspection and maintenance. Units

incorporate EU4 grade filters on the extract

side and EU7 grade filters on the supply side.

Each DERV unit is supplied with a fan speed

controller to allow on/off switching and setting

of the air volumes either at the unit or

remotely.

DERV units are available with a range of

options which include UV sterilisation tubes,

heat exchanger anti-corrosion coatings, sand

trap louvers and duct balancing dampers.

Four sizes of unit are available to suit the

space size and ventilation rate required with

the largest single unit supplying up to 500

litres/second.


Preserve your Conditioned Indoor Environment with Air Curtains

Air Curtains

10

Due to increasing environmental

concerns and high energy costs there

is a need to keep doors CLOSED to

prevent warm air and moisture ingress

in hot and humid climates.

To encourage high pedestrian footfall or

goods traffic, an “open door” policy is

often followed leading to the converse

need to keep doors OPEN.

SPC’s range of air curtains drive a powerful

stream of cool air across an open doorway,

which reduces the inward draught of warm air,

humidity and pollutants. Air curtains make life far

more comfortable in

busy locations such as

shops, factory loading

bays, and public

buildings by “locking in”

the conditioned air.

The correct specification is vital for air

curtains - incorrectly specified units can

increase heat gains and all units must be sized,

selected and positioned carefully.

SPC will advise on the correct solution for you

from their range of commercial and designer

units on offer.

Key reasons to install an Air Curtain

• Reduces energy loss by up to 80%

• Minimises temperature fluctuations

• Immediate comfort

• Maintains air conditioned environment

• Exhaust, Smoke & Fume Control

• Dust & Pollen Control

• Insect Control

• De-stratification
