Introduction Laird Outdoor Cooler Series is an Air to Air thermoelectric assembly that uses impingement flow to transfer heat. It offers dependable compact performance by cooling objects via convection and is designed to provide cooling for a wide range of outdoor environments in the telecom, industrial and kiosk markets. They are intended to work in an open loop system or if purchased with a bi‐directional controller in a closed loop system with feedback control. Heat is absorbed and dissipated thru high density heat exchangers equipped with air ducted shrouds and brand name fans. The heat pumping action occurs from custom designed thermoelectric modules that achieve a high ...

Installation and Operation Instructions Reducing the passive heat load is critical to yield the highest efficiency out of an Outdoor Cooler and maximize service life. It is important to insulate the walls of an enclosure with as much insulation material as permissible without interfering with nearby electronics or system level obstructions. Proper insulation of the enclosure can result in sizing a smaller Outdoor Cooler unit and power supply, which can reduce total system costs. The Outdoor Cooler is mounted onto a cabinet wall with “Hot Side” mounted external to cabinet. This is ...

Schematic Outdoor Coolers come with a durable simple to use cage clamp. Wires should be stripped back 6 mm’s in length and inserted into connector. Connector can accommodate wire sizes of 12 to 28 AWG. For input power to TEM 16 AWG stranded copper wire is recommended. For input power to fans 18 AWG stranded copper wire is recommended. Electrical connection cold side: Ext. FAN + Int. FAN + TEM + TEM – Int. FAN – Ext. FAN – Warning: Do not reverse current or use PWM – regulation on fan supply. Internal schematic of Outdoor Cooler Unit. (24 Volt schematic shown) Connect external fuse in line with input power connector to protect input ...

Serviceability No special maintenance is required when using Laird Technologies Outdoor Coolers. For continued optimal performance and extended life of the unit, it is recommended to clean the (internal/external) heat sinks and fans periodically as they will accumulate dust from outside contaminants over time. If a unit is not performing properly consult with Laird Technologies. Warranty Laird Technologies Outdoor Coolers are manufactured in an ISO 9001:2008 facility.
