Laird Enables Modernization of Telecom and Electronic Cabinets with New Power-saving High Performance Cooler

New AA-230 Cooler with Horizontal Mount protects electronics from heat, ensuring maximum uptime and low total cost of ownership.

Global technology leader Laird (LRD: London) releases the new AA-230 Series Cooler designed to protect electronics used in telecom, industrial, medical, and analytical applications.

Electronics can overheat and even fail if exposed to temperatures outside the proper limits. In telecommunications for example this means mobile phones can lose their connection, making temperature control a crucial aspect of efficient and reliable operation.

Standard air-to-air temperature control systems with vertical mounts are often too large to fit inside a telecom or medical enclosure, so instead they are mounted on an exterior wall to provide temperature control to the entire space inside.

"Too many electronic cabinets are cooled needlessly with expensive bulky compressor based air conditioners," explains Anders Kottenauer, Senior Vice President of Laird's Engineered Thermal Systems business. He adds, "There’s no need to cool the entire enclosure, it’s a waste of time, energy, and money. That’s why we designed the AA-230 to be a smaller, more efficient option allowing users to cool only the electronics requiring temperature control while lowering total operating costs."

The AA-230 solves this problem by utilizing a horizontal mount orientation that makes it able to accommodate short partitioned shelf heights. This means rather than cooling the entire cabinet, now a single smaller cooler can be mounted inside the enclosure to protect only the specific electronics that require cooling, which translates to energy cost savings.

Because of its innovative design, Laird’s new AA-230’s steady state construction requires less maintenance than standard compressor based air conditioners. It also creates energy savings by maintaining the appropriate temperature range using less energy than standard air-to-air systems due to its high coefficient of performance (COP).

The AA-230 Outdoor Thermoelectric Cooler is an Air-to-Air thermoelectric assembly (TEA) which can be used indoors or outdoors. It uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via convection. The AA-230 has 230 Watts of cooling power and at ?T=0°C.  Heat is absorbed and dissipated thru custom designed heat exchangers with high aspect ratio.  The cold side air ducts can be oriented in any direction to accommodate obstructions and maximize circulation. The heat pumping action occurs from custom designed thermoelectric modules that achieve a high coefficient of performance (COP) to minimize power consumption.


Key System Features:

  • Horizontal mount to accommodate tight spaces
  • Flexible cold side air duct orientation
  • Input power accommodates a nominal/float voltage of 24/28 or 48/56 VDC
  • Power cycle tested up to 70K cycles
  • Environmentally friendly solid state operation with no CFC refrigerants
  • Cooling and heating in the same unit to maintain compact form factor.


The AA-230 compliments the product family of Outdoor Coolers but can also be easily retrofitted as a substitute for compressor based air conditioners used in medical diagnostic and analytical instrumentation for cooling and heating applications where maximizing system uptime is required.
