Introduction to Bosch Thermotechnology

Bosch Thermotechnik GmbH is a leading supplier of resource-efficient heating products and hot water solutions in Europe. In fiscal 2013, the company generated sales of 3.1 billion Euros (68% outside Germany) and employed approximately 13,500 people. Bosch Thermotechnology has strong international and regional brands and manufactures a diversified product range in 21 plants in 11 European, North American and Asian countries. In 2013, Bosch Thermotechnology invested 129 million Euros in research and development. Intelligent networks and local systems for heating, ventilation, air-conditioning and electricity generation are fundamental technologies for the future building standard, which will generate more energy than is used.

In Southeast Asia, Bosch Thermotechnology has been established in the middle of 2011 to provide a closer support to its local customers as well as to further extend its market position. The regional headquarter office is based in Singapore, overseeing business development in the Southeast Asia region. Nowadays, Bosch Thermotechnology has successfully established sales offices in Indonesia, Malaysia, Singapore, Thailand,

Philippines and Vietnam, with a representative office in Myanmar.

Bosch Thermotechnology is mostly known in Southeast Asia for its large-scale, commercial and industrial boiler systems. In 2014, the product portfolio has been extended to cooling solutions which are energy efficient, eco-friendly and high quality products for commercial and industrial applications which help our customers to increase comfort and reduce energy cost.

A comprehensive range of renewable heat pumps, chillers, fan coil units and air handling units meets almost all kinds of requirements from buildings like office, hospital, hotel, shopping mall or industrial plants.

Bosch Climate 5000 Water Cooled Screw Chiller is an efficient, compact, reliable, and environment friendly product engineered with state-of-art technology and most advanced industrial design. It has a capacity range from 290kW to 1505kW with 14 different models.

Characteristics

High efficiency Partial Load Energy efficiency up to 6.1, step control is

applied as default; With high efficiency compact semi-hermetic screw

compressor, low compression ratio avoids over compression and short compression;

Design condition has been optimized to be as close as to the actual application, performance in part load increased significantly.

High efficiency evaporator, Fully counter flow heat exchanger, high efficiency.

Precise control by high precision and fast responding electronic expansion valve, adjusted with compressor synchronously; Start steadily, prevent the refrigerant(liquid) from spattering into the compressor.

Optimized refrigerant pipe design, Zero pressure drop (P=0kPa) ball valve increase efficiency & performance.

Control High precision temp. sensor(+/-0.3oC), working range 20~150oC; Superheat degree control SCH, fast responding on refrigerant side, more accurate; Adopt “ fuzzy control” principle to control the compressor capacity output based actual demand, thus reducing power consumption.

Environment friendly Refrigerant: R134a, ODP=0, GWP=0.29, no damage to

the ozone layer Less refrigerant charge, Less GWP influence, more

environment friendly e.g. WLWC-520C3A, refrigerant charge=172kg, and the flooded type for same model, refrigerant charge=340kg

Low running noise 2~3dB(A) lower comparing to conventional products

with optimized system design and noise reduction measures.

1) Low noise compact screw compressor(mechanical and electromagnetic noise)

2) High performance noise insulation (Armaflex) for key noise points

Extra 5~8dB(A) noise reduction can be achieved with optional noise reduction device.

Safer Power isolation switch for safety enhancement Extra safety with in-built power protection guard Equipment protection class IP 30 Quick release of system pressure by 1 inch safety

valve

User friendly HMI Sensitive LCD touch screen controller with excellent

user experience. Easy access to system running parameters and

running curves. Historical running records & failure records are

stored up to 80 records. Authorized access is included. Weekly-timer function is included. Self-Diagnostic and alarm function is included. Failure manual reset function is included.

Easy installation, maintenance and service One side water pipe connection, easy for connection

and space saving; Clamp type pipe connection easy for connection and

maintenance; Ball valve on the discharge pipe and refrigerant pipe,

1/4 circle from full open to full close, and rotation restriction on both full open and full close process, easy for maintenance.

More reliable Multiple System Protections:

-Power protection -Electronic protection -Overload protection -Expansion valve protection -Oil pressure difference protection -Oil position protection -Circulating water flow protection -Cooling water flow protection -Low pressure protection -High pressure protection -Suction/discharge pressure difference protection -Anti-freezing protection for chilled water

Compressor working time balance technology utilized.

The unit should be installed at a location that fulfils the following requirements: The unit should be in a special device room. The foundations must be level and stable enough to ensure that no vibrations or operating noises occur when

the unit is in operation. The unit should be installed in such a way that it is only accessible to authorized, trained and technical

personnel, and use appropriate equipment to keep unauthorized persons away from the unit. There must be sufficient clearance around the unit to carry out maintenance or repair work. Make sure the leaking media do not damage the installation location or the environment. Choose the installation location so that operating noise does not cause a disturbance. There should be drainage around the unit foundation in order to drain out the water in the system when the unit

stops or is in the maintenance. There should be no pipes or wiring pipe above the compressor.
