Product Introduction

About the Cooling System of Greenhouse, our company is specialized at the products of cooling pads and fans, usually used cooperatively. The cooling pads are installed on one side of the greenhouse, the exhaust fans, the other. (The air-circulating fans are installed in the greenhouse.) The exhaust fans eject the air from the greenhouse (The air-circulating fans promote the circulation of the air in the greenhouse), negative pressure formed in the greenhouse. The air enters the greenhouse through the cooling pads, resulting in the effects of cooling, moistening and air-dedusting.

Fans

(1) Heavy-Hammer Type Exhaust Fan

A) The frame, structured by thick galvanized steel sheet which is has strong anti-corrosion property, is made by the CNC bending machine, CNC shearing machine and the technology of CNC punch processing.
B) The frame has strong hardness and great toughness, which can be in service for long time.
C) The automatic belt regulator is equipped to preventing the belt from falling off, not necessary to regulate manually during the service period of belt.
D) The blades, driven by the belt through the motor, are shaped by reasonable style and angle, punched and twisted to be framed, passing the test of dynamic balance and the test of static balance, ensuring the strong blasts of air through them and the low noise that is caused.
E) The louver, made by aluminum alloy or galvanized steel, has the special switching structure, pneumatic type, ensuring itself turn on and off perfectly and functioning as the role of wind-proof, rain-proof and dust-proof.

(2) Push Pull Type

A) The louver is controlled by the automatic control system, ensuring the switching actions automatically, rain-proof, wind-proof and dust-proof.
B) The motor is effective and energy-saving, the IP grade of which is IP55 and the insulation grade of which is the grade of F.
C) The automatic belt regulator is equipped to preventing the belt from falling off, not necessary to regulate manually during the service period of belt.
D) The centrifugal opening structure is made by the nylon, reinforced and painted, high toughness and hardness. It can be in service for a long time. 

(3) General Type Exhaust Fan

A) The automatic processing technology is applied on the frame of the fan, which is made by the extra-thick galvanized steel sheet, very hard and resistant to corrosion strongly.
B) The blade is twisted and punched, suitable titled angle ensuring the optimal level of the blast capacity.
C) The special switching structure is applied on the louver, ensuring its opening and closing completely and realizing the rain-proof function after closing.
D) The safety net on the back and the motor inside can be easily installed and dismantled. 

(4) Air-Circulating Fan

A) The motor has the great performance of rain-proof, wind-proof and dust-proof, passing the destructive test of 360 hours. It works in low noise and can be in service for long time.
The shell is designed by the principle of air collector, advanced energy-saving technology, and thermally protecting auto-system.
B) The blade is punched by the light aluminum materials, large tilting angel, great blast capacity and low noise.
C) The accessories are made by the superior thin steel sheet, light and beautiful, easy to install.
D) The blast capacity can be optimized and designed by CAD, ensuring the air circulation and uniformizing the temperature, humidity, and the concentration of CO₂.
E) You can choose the different frame, made by stainless steel or painted steel. 

Cooling Pad
