Page 4: Overview
Overview Thank you for your purchase of the ISC Inc Special Purpose Air Conditioner. Our air conditioning equipment is carefully designed to cool and dehumidify the air in electronic component enclosures. ISC Inc has designed air conditioners for all types of electronic equipment enclosures providing capacity from 1,000 to 20,000 BTUH. -
Page 5: Moving The Air Conditioner
Delta-T air conditioners operate as a “closed loop” system with no exposure or introduction of outside air. This ensures that the enclosure is separated from, and is not contaminated with, ambient air, dirt, chemicals, dust, moisture or foreign matter so that sensitive enclosure components are protected and are kept at your required operational temperature. -
Page 6: Preliminary Testing
The cooling is done using a simple refrigeration cycle. A product of this simple refrigeration cycle is excess humidity that condenses to a liquid. Delta-T air conditioners are designed using an advanced refrigeration cycle and are equipped with a Condensate Removal System that changes the excess humidity liquid into a vapor which is then vented to the atmosphere. -
Page 7: Mounting The Air Conditioner
Mounting the Air Conditioner Using the template supplied, determine where the air conditioner is to be mounted and assure that all required cuts and holes will not interfere with or damage the enclosure or its contents. Assure that there is a 3” clearance between walls / obstructions and the air conditioner for the condenser supply air and return air flow so that it is not restricted. -

Celsius Programming Celsius Programming option allows the user to control the Delta-T Air Conditioner in SI units. This feature can be programmed into the digital temperature controller at time of manufacturing. 4421 Tradition Trail ● Plano, Texas 75093 ● 972 -964-2700 ● 800-836-7472 URL: www.iscenclosurecooling.com... - Page 11 Ethernet/IP Controller Output This option provides the ability to communicate with the Delta-T Air Conditioner controller via the Ethernet/IP protocol. You can monitor and control all settings from a remote location with a PLC.
- Page 12 Note: The Remote Controller option is required for high pressure wash-down applications. Corrosion Protection The copper tubing and aluminum fins used in the air conditioner refrigeration circuit are subject to damage in the presence of corrosive chemicals such as hydrogen sulfide, chlorine, etc. Condenser and evaporator coils are available with electrostatically applied epoxy coating to prevent corrosion.
