Heat exchanger

WTK, leading manufacturer of water heat exchangers has an ultra-decades old experience in this field distinguishing itself for a continuous technological and manufacturing improvement, product flexibility and service to customers. The range of products (shell & tube evaporators dry-expansion and flooded type, shell & tube condensers also for maritime application, brazed plates, oil separators, liquid receivers, oil coolers, economizers, Desuperheaters) is suitable for applications related to the air conditioning, commercial and industrial refrigeration, process, heat pumps, heat recovery and others. It consists of heat exchangers shell & tube type suitable for capacities from about 20 kW to 2500 kW, brazed plates for capacities from about 5 kW to 400 kW, oil separators single and double stage for suction volumes beyond 2500 m3/h, horizontal and vertical liquid receivers from about 30 litres to 1000 litres and over.We are the dealers of WTK manufactured heat exchangers.
Shell And Tube Chiller
The series SCE represents a technological and innovative revolution of "single pass" dry expansion evaporators, or in perfect counter-flow, designed and produced to meet requirements for very high efficiency. Optimized for applications using refrigerant gases R134a and HFO, these S&T guarantee the best performance of the chiller to halved approaches between the evaporation temperature and the cool fluid outlet temperature against the U-tube models.

Some of the models are:
  • SCE 23 C 4 P
  • SCE 33 C 4 P
  • SCE 53 C 4 P

Shell And Tube Condenser
The S&T condenser series CF is of high performances with all kind of the most common refrigerants (HFC, HCFC, HFO). The special pattern of the exchanger pipe, designed and machined by WTK, can be manufactured in a wide range of lengths so to meet all the various performance and foot-prints requirements.

Some of the model are:
  • CF 60 C 4 P
  • CF 80 C 4 P
  • CF 105 C 4 P
  • CF 135 C 4 P

The performance and efficiency of the brazed plate heat exchanger (BPHE) have been proven through 30 years of constant development to ensure high thermal efficiency leading to energy savings in air conditioning systems.

(Micro-channel Heat Exchanger) Sanhua MCHE. Micro Channel is the new generation in heat exchanger for the HVAC Industry.we are the dealers of sanhua manufactured MCHE. The key benefits of these mche are as follows, it improves efficiency by 30%, refrigerant charge reduction by 30%, mche is lighter in weight, and compact design.

Heat Less Condenser
In all the above models tubeless form of construction is employed. This is achieved by the use of highly ductile steel fins having funnel type collars formed, (each funnel); which are subsequently copper brazed in a inert atmosphere fur- nace. This method of construction gives the highest possible conductivity as the gas virtually flows through the fins. The new internal construction of the tubeless condenser passages combines three ac- tions.

  • increases the refrigerant flow turbulen- ce,
  • increases the primary heat exchange surface since the corrugated internal walls offer greater surface than smooth wall tubes,
  • diminishes the thickness of the liquid film adhering to the surface which is an obstacle to the condensation of remai- ning vapour.
