STANDARD ON ALL THERMAL EDGE AIR CONDITIONING SYSTEMS

Thermal Edge Condensate Control is accomplished by routing refrigerant hot gas through our condensate boil off pan. The pan is located ahead of the condenser in the hottest point in the refrigerant system where the hot gas temperature is 180° F to 260° F.

Condensate is evaporated and the vapor is discharged by the condenser blower to the environment. Additionally, this condensate evaporation helps to pre-cool the hot gas, lowering the running amps and making our industrial air conditioner more efficient. By utilizing this pre-cool method, we lower the overall use of energy.  This condensate boil off pan has enough water storage capacity to dehydrate the air in your equipment enclosure and vent it off without overflow so long as the enclosure doors are closed.

In the event that the enclosure will remain open, Thermal Edge does supply an Emergency Overflow Fitting on all of our units. Use of this Fitting is only for extreme open-door applications and should not be utilized in typical or even heavy applications.

1. Condensate forms on evaporator and drips into a pan
2. The drain forms a P-trap to maintain Closed Loop Performance
3. Condensate collects in pan among loops of super-heated refrigerant to boil off normal build-up of condensate. Water vapor blown through condenser coil increases performance

Operation

Thermal Edge air conditioners will lower (or increase as necessary) the temperature inside an enclosure to ensure its proper operational temperature. Our air conditioners, when sized properly, will provide cooling or heating automatically controlled by the digital controller.

Thermal Edge air conditioners operate as a “closed loop” system with no exposure or introduction of outside air. This insures 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.

An air conditioner is designed to dehumidify and extract heat from an area, or provide heat to an area. The cooling is done using a simple refrigeration cycle. A product of this simple refrigeration cycle is excess humidity that condenses to a liquid.

Thermal Edge 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. In the event of excess water vapor when the enclosure door has been left open there is an overflow hole on the bottom of every unit. Please contact Thermal Edge Inc. if you encounter excess water coming from your air conditioner.

Unit Label

Each air conditioner has a unit label, be sure to record the data from the label to the template below and keep this information in a safe place for warranty and ordering parts. To prevent damage to equipment, electrical panel and wiring, and to prevent personal injury, assure that the power source is compatible with the equipment before operating. When recharging, refrigeration type and amount must be the same as shown on the unit label or air conditioner will not operate properly or may be damaged and may result in the warranty voided and UL listing voided.

Preventative Maintenance

Air to Air Heat Exchangers may require regular cleaning of the condenser air inlet section depending on the environmental conditions. Restriction to the flow of air over the condenser section will degrade the performance of the equipment, reduce cooling and can damage the fans.

Refer to Field Serviceable Parts section in this manual for details on parts that can be changed to help increase the uninterruptable life of the heat exchanger.

Condenser Air Inlet Cleaning

In the event of excess dust or particulates, clean the condenser air inlet section with a soft water spray or compressed air not to exceed 90 psi.

Condenser and Evaporator Fans

Thermal Edge Air to Air Heat Exchangers use high efficiency, long life, sealed ball bearing fans engineered for optimum performance that require no maintenance.  Fans are removable and employ plug-in electrical connections.

Field Serviceable Parts

Thermal Edge carefully designs and selects components with the maximum life expectancy.  Due to OEM manufacturing tolerances, poor unit maintenance or extreme operating conditions, components may fail before their maximum life expectancy. The table below lists parts that are serviceable in the field by an Air Conditioner Technician.

Options

The Thermal Edge Plastic & Metal Series Filter Fan Packages may be ordered with the following options. Review the list below for the specifications and functions of the option(s) that apply to your unit.

Preventative Maintenance

Filter fan packages may require regular filter replacement depending on the environmental conditions. Restriction to the flow of air will degrade the performance of the equipment, reduce cooling and can damage the fans. Restricted air flow due to neglecting a dirty filter may cause fan to overheat. Continuous operation in this condition will eventually damage the equipment and void the warranty.

Refer to Field Serviceable Parts section in this manual for details on parts that can be changed to help increase the uninterruptable life of the filter fan package.

Filter

Replace filters are readily available at Thermal Edge; a good preventative maintenance schedule is crucial to insure filter fan package optimal performance.

Fans

Thermal Edge Filter Fan Packages use high efficiency, long life, sealed ball bearing fans engineered for optimum performance that require no maintenance. Fans are removable and employ plug-in electrical connections
