INTRODUCTION: Vapour Degreasing is the simplest and the most efficient method of removing oil and grease from

metal parts before surface treatment, finishing processes such as Electroplating, Phosphating,

Anodizing, Industrial Linings and Heat Treatment before overhaul and during maintenance and

repairs.

PROCESS:

The solvent in the tank is electrically heated to a

specific temperature. When the solvent attains the

boiling point, vapour is created. This vapour is

restricted inside the tank by water cooling systems

(cooling tower / chiller) so that vapour remains

inside the tank. When greasy /oily article is

suspended in vapours, the solvent condenses on it

dissolves the oil and falls back into the sump. The

cleaning action continues till the article being

cleaned reaches the temperature of solvent vapour.

By the time all traces of grease and oil have been

removed. The vapour will penetrate into the deepest

recesses of the articles and clean them in the matter

of minutes.

FEATURES:

• Special adopted design for minimum solvent

losses.

• Efficient water separator for reclamation.

• Efficient, durable and easily removable type heating elements.

• Efficient copper cooling coils and cooling jackets provide a good arrangement for solvent

condensation.

• Control for heating coils are provided which trip

off when it reaches a set temperature or if the

cooling is insufficient.

• Electric timer for work control.

• Temperature indication of water inlet/outlet

temperatures

• Efficient way of filling solvent into the tank

through filling port.

• Dip stick to check the level of solvent.

• Uniform quality of degreasing throughout.

• A very efficient, time saving and labour saving

equipment.

• Very little maintenance

• No fire hazard.

EQUIPMENT DESIGN FEATURES:

Equipment design follows the

selection of a cleaning cycle and work

handling method. Important design

considerations to achieve effective,

economical, and safe operation are

summarized below.

SIZE OF EQUIPMENT:

The size of the tank is determined by

the dimension of the largest workload

that will be suspended from the hoist

Ideal to have at least 50% greater

vapour or working area than that

required for the size of the largest

part. Otherwise, the work going in and

out will act as a piston to displace

solvent vapours out of the machine.

FREEBOARD ZONE:

Freeboard is the distance from the top of the vapour level to the top of the degreasing tank.

Optimum freeboard height-to width ratio decreases, solvent losses

TYPES OF HEAT INPUT: The heating for the degreaser can be designed as per client’s need /

existing arrangement viz. electrical, hot water, steam or thermic fluid.

The control of the degreaser is essentially the control of the solvent vapour. The control of

vapours at the desired vapour level is accomplished by the flow of water or other coolant through

coils and a jacket around the walls.

COOLING COILS AND WATER JACKET:

A welded jacket is sometimes used around the tank perimeter at the vapour level. The prime

function of the jacket is to keep the wall of the freeboard zone cool to prevent vapours from rising

because of convection.

Coolant flows through closely spaced turns of pipe positioned to control the vapour level of the

degreaser. These can consist of either a helical coil positioned in an offset compartment leaving a

clear sidewall within the degreaser body or multiple passes can be provided around the inside

perimeter of the tank.

THERMAL INSULATION:

The area around the vapour zone will be jacketed for

thermal efficiency.

WATER DISTILLATION & SLUDGE REMOVAL PORTS:

These will be provided at suitable places on the tank

LID:

A light weight FRP lid will be provided to prevent wastage of

trichloroethylene during idle times.
