Brand Name: HX
Model Number: DD
Place of Origin: Tianjin, China (Mainland)
Our company is mainly in the production of air coolers used in food production and processing
under different temperature requirements for various rooms, such as processing room, pre-cooling room, exterior and interior packing room, cold storage and freezing room. Air coolers
are formed by shell, liquid device, the finned tube group, defroster, water dish and
the axial flow fan.
>>> Features:
1. Tube group adopt regular triangular permutation and combination where optimizing design
has been practiced in fin shaping, spacing and length of tubes which improve air coolers of
heat transfer coefficient.
2. Tube and fin are composed of mechanical expander. Tight integration between the two,
reduce the temperature impact.
3. Low noise refrigerator special fans are chosen which has long using life.
4. Select durable high quality stainless steel electric heat pipes which have silicon rubber sealing
end are used to defrost. In the case of water defrost, we recommend special defrosting leaching
tank, whose benefits are defrosting much evenly, and prevent overflow and splash of blunt water.
5. For high temperature air cooler, using insulation heating technology, effectively prevent
condensation and water dripping. Superior machining environment ensure food safety.
6. Air coolers full range of the company. Design of Freon, ammonia, ethylene glycol, etc. These
products can be widely used food chilled, frozen, both in production and processing and other
environment with various needs of low temperature. We can also design and manufacture of s
pecial purpose air coolers under specific requirements.
