turbular refrigeration heat pump system Coil-in-shell heat exchanger

consist of high efficiency finned coiled pipe and carbon steel shell, cold and heat liquid flow separately between shell and pipes.

Product feature

1. High thermal exchange efficicieny

(1) Inner tube is high efficiency dual-healix finned copper;pipes, and heat exchange surface is 4 times that of smooth pipe. 
(2) Fin on the internal and external surface will increase the turbulence of water and refrigerant, which will increase the efficient of heat exchange. 
(3) With special process, the compact structure of heat exchange coiled pipe will well ensure the heat exchange between refrigerant and water.

2. Safe

(1) There is no welding point on the copper pipe, so it can make sure the system work stably for a long time. 
(2) There is dead zone in the water passageway, water flow at a balance speed. And heat exchanger will not easyly get frozen at part area. 
3)Water gap is at the lowest position of heat exchanger, and that will be convinient for drain away water in cold weather.

3. Small

(1) The compact structure will help save room for a system, and it is convinient to set other part of a system, so it can decline the overall dimension of all system.
(2) There is reservoir inside, and that will safe a lot of space for a system.

Application

Coil-in-shell heat exchanger is widely applied for: heat pump water heater, air source heat pump water heater,central air-conditioning,water source heat pump,swimming pool device, heat recovery system, heating, drying etc.

1.Carton Packing: Only for small size, light weight products.

2.Plywood Case Packing: High resistance of burst strength, ring crush strength and tearing strength.

Q:What Kinds Of Heat Exchangers Does HZSS Have?

A:The HZSS heat exchangers include: coaxial heat exchanger, shell & pipe heat exchanger, evaporator condenser, Integrated micro-channel heat exchanger, micro-channel cooling plate, vapor chamber, micro refrigeration system etc.

Q:Usually how much is the capacity of coaxial heat exchanger?

A:At the conventional working condition, the max. capacity of one single tube in tube heat exchanger is about 10 tons of refrigeration. If we need more capacity, we have to make heat exchangers in parallel.

Q:what is the advantage of embossed coaxial heat exchanger?

A:After the inner tube is embossed, the connecting surface of refrigeration between inner tube and external tube is enlarged, the heat transfer amount is increased. As we test, the heat transfer amount of embossed tube is 150% of the smooth one using the same length of tube. So the coaxial heat exchanger will be much smaller.

Q:How to seek for after-sales service?

A:If you are not satisfied with the products you have got from HZSS, you can contact the sales manager who sold you the heat exchangers. Warranty usually start from the day when heat exchanger is installed and last for 12 months and warranty only contain the defect of manufacturing and material, but under no condition will the warranty last more than 15 months. In warranty period, HZSS will fix the product for free, and if the heat exchanger cannot be fixed than we will change a new one for you. Beyond warranty period, the repair service will be paid for.
