WEATHER PROOF CHILLERS
Air Cooled Chillers and Water Cooled Chillers are available from 1 TR to 750 TR with temperature ranges from +40 C to -50 C. Our Chilling plants ensure easier control and maintenance of the system. IP 55 Panel protection for weather proof usage.
Tipo Heat Exchangers Technology can now be retrofit to existing chiller systems. Depending on your climate and chiller system usage, operating efficiency can be increased by as much as 60% using our Patented Economizer control system. Our engineers have carefully selected and matched OEM Sensors for optimized integration with our chiller Economizer Technology
Quick-Response Sensor
� Etched Teflon Lead wires
� Well-Vented, Light-Colour Sensor Guard
� Weather Tight or Weatherproof Enclosure
� Wide Selection of Temperature Sensing Elements
� Limited Lifetime Warranty
Outside Air Units are designed to be mounted outdoors. The UV-resistant plastic shield keeps the sensor out of the sunlight and allows for excellent air circulation. The Outside Air Unit comes standard in a Weather Tight (EU) UV-resistant enclosure which carries an IP 66 rating (similar to NEMA 4X) and is light in colour to reflect sunlight and minimize reading error. Outside Air Units are also available in a cast aluminium Weatherproof (WP) enclosure which carries a NEMA 3R rating.
All Outside Air Units have etched Teflon lead wires and double encapsulated sensors to create a watertight package that can withstand high humidity and condensation and perform under real world conditions. This is especially important in an outside air application which can be exposed to rain, snow and large temperature swings.
