Product Overview:
EF serlies air coolers are mainly used for quick-freezing or low-temperature quick-freezing cold store
1. Enclosure: High-quality galvanized steel plate sprayed with powder coating(silver gray RAL90o6), with desirable corrosion
resistance; plates on both sides are designed with hinged structure, which is convenient to operate;
2. Double water tray design: The outer water tray is designed with edge structure with angle, which makes the water drain
smoothly without any dead angle; the inner water tray is designed with sink structure made ofaluminum plate, and the
condensed wateror defrost water is directly discharged into the drainage outlet of the outer water tray through the inner water
tray:
3. Designed with overall stretching large arc high air tube, it has the characteristics of excellent air guiding effect
4, coil: The aligned tube pattern 50 x 5o mm features large heat transfer area, low heat transfer temperature difference;
5. Cormugated aluminum sheet made ofhydrophilicaluminum foil, with the sheet spacing of6.0mm,9.0mm and 12.0mm to meet
different operation requirements;
6. Fan; The fan with blowingairand operating temperature of 45 C,which isequipped with a motor with higher power and
higher wind pressure, to ensure the residual pressure outside the machine, reduce the wind speed on the surface of the food,
lower dry consumption, and improve the quaiity of food freezing;
7. Defrosting; The electric defrosting is adopted in the standard manner, and the stainless steel heating tubes are distibuted in
the coil fins and the inner water tray, which can bring about desirable defrosting effect; the heating tube hole in the coil is
equipped with an aluminum sleeve to improve the efficiency of defrosting effect;
8. The lP65 waterproof junction boxand waterproof connectorsare used, with better waterproofing; the fan and the heating pipe
are wired separately, which can lead to high reliability;
9. The outlet of the air cooler is equipped witha needle valve, which is convenient for users to test the pressure,
10. It is subjected to strict pressure test at the pressure of 23bar;
1L. The expansion valves, heating band of fan tube and other parts can be pre-installed according tocustomer's needs;
12.It is compatible with R404A, R507A, R448A, R449A, R22 and other refrigerants

Zhejiang kaidi refrigeration equipment co.,ltd was established in 1995.It is a refrigeration equipment manufacturing company integrating research and development, processing and manufacturing, sales and commissioning services. The company is headquartered in Cangzhou City, Zhejiang Province. The company covers an area of 50,000 square meters. It has more than 30,000 square meters of modern factory buildings and more than 6,000 square meters of offices. It is equipped with advanced CNC processing equipment and high-standard testing laboratories. The company has a senior professional technical team and an experienced manufacturing team.

Since its establishment, the company has passed the ISO9001 quality management system certification, and has obtained industrial product production licenses and special equipment manufacturing licenses of the People's Republic of China (pressure vessels D1, D2). At present, the company's products mainly include air coolers, air-cooled condensers, shell and tube evaporators, shell and tube condensers, fully enclosed / semi-closed / screw compression condensing units, integrated compression condensing units and larger piston / screw Single and double-stage parallel units, ultra-low temperature air source heat pumps, air source heat pump drying units, water (ground) source heat pumps, etc.

After years of development, we not only have a complete product line, from chiller products and condenser products to different types of compressor units, which can meet the application requirements of different scales and different grades, and we attach great importance to the design support capacity of engineering refrigeration systems. The construction can provide professional technical support for the whole process of the project's pre-design, equipment selection, installation and commissioning to ensure the overall operation of the project. Based on the principle of customer-oriented, we have established a sound modern enterprise system and a comprehensive and effective quality management system, and have a pre-sales and after-sales service system that reflects promptly and thoughtfully.

"Kaidi" brand refrigeration products have a high reputation in China, and have won praise and recognition from customers. At the same time, they have also exported to Russia, Spain, Japan, South Korea, Malaysia, Vietnam and other countries, and have a place in foreign markets.
