| 1. Producta. This device circulates cooling water heated by boiler into the core inside, passes the air from motor & fan through the core, and exchanges with cooling water by the difference of air temperature.b. The material of product is 99.9% high purity of brass plate & copper, by using this material, this device has excellent heat transfer & efficiency.c. For farming, in summer, by using cold wind, and in winter, by warm wind, so this is heat exchanger of ventilation type. 2. Functiona. Prevention of winter breaking When you fix the temperature controller, and the temperature is under the (*) degree, it works automatically, to prevent from winter-breaking of radiator & surrounding facilities.b. Temperature fixing function It keeps the fixed temperature by automatic temperature controller, and makes low & high temperature surroundings for crops.c. Prevention of over heating By installing temperature sensor on cooling water, and the over heating prevention device which cuts off the power automatically is built in. 3. Meritsa. Low noise and easy installation, low installation costb. It can be installed anywhere like independent or continuous house.c. Temperature control & radiator efficiency is high, so you can save the cost of oil.d. When you use by mixing antifreezing solution (30%) & oil, this prevents from corrosion by underground water, so can guarantee long durability. |
