Laird LA5000 Series

New in February 2023

LA5000 Liquid to air heat exchangerThe new LA5000 Series recirculating liquid-to-air heat exchanger offers improved thermal performance maximizing system uptime. As a water heat exchanger, the 5000-watt unit provides dependable compact performance while removing large amounts of heat from a liquid circuit.

The LA5000 is designed to function above ambient temperatures, eliminating the threat of condensation. To avoid costly failures, the system operates on a full-time scale; continuously monitoring system liquid levels and notifying users if preventative maintenance is needed. A dedicated tank prevents air entrapment within the liquid, stopping air bubbles from getting drawn into the liquid and damaging the pump. The added instrumentation results in a more robust design, and with proper care and maintenance, users can expect over 10,000 hours of continuous, maintenance-free operation.

For improved thermal performance, the LA5000 cooling system uses a higher-performing heat exchanger and a more efficient fan, reducing operating noise and the temperature difference between the liquid and the air by a factor of 2. To ensure a maximum flow rate over a wide operating range the coolant is recirculated using a high-pressure pump. Heat from the coolant is absorbed by a radiant heat exchanger and dissipated into the ambient environment using brand name fan. Compared to standard liquid chillers that operate below ambient temperatures, the LA5000 liquid cooling system operates above ambient temperatures, at a lower cost.

Typical Applications

Designed to maximize system uptime, the LA5000 heat exchanger is ideal for:

  • Immersion cooling and bulk heat removal in particle accelerators
  • Linear accelerators
  • Cyclotrons
  • Semiconductor fabrication equipment
  • Medical X-ray
  • Industrial X-ray scanners
