General information

Laird has acquired the manufacturer Klüver Aggregatebau GmbH in Kaltenkirchen near Hamburg in May 2012. The product range includes aggregates of the cooling and heating systems for research, industry and medicine.
Liquid Cooling Systems (LCS) are ideally suited for the thermal management of machinery and equipment by using a coolant for heat transfer. Most engineers are concerned about the introduction of fluids into the electronics, but properly planned and assembled the system is absolutely secure. LCS have several advantages over conventional air cooling systems:
- high heat pumping capacity
Liquid heat exchanger can reduce the thermal resistance over conventional heatsink fans by a factor of 10 or more.
- high heat flux
LCS can store up to 5 times as much heat per surface dissipate as your traditional air cooling systems. This is a great advantage, especially in the densely packed electronics.
- targeted heat dissipation
LCS enables the integration of small heat exchanger on the heat source itself The heat is then dissipated in a targeted and transferred to a remote location -. An advantage over air cooling, where very complex and large-area air must be blown through the electronics.
- fast cooling
The cooling time depends on the cooling performance. LCS have a larger power than conventional cooling systems, and therefore reduce the time to reach the target temperature.
- less noise
Systems with high heat dissipation requirements (1kW or more) require much larger fan to produce the air flow, which dissipates the heat, as LCS. This makes the fan, as opposed to LCS, louder and creats higher vibrations in the system.
Application examples:
- Medical imaging systems (eg: x-ray)
- Industrial and medical laser systems
- Digital printing, centrifuges
- Semiconductor manufacturing

Various Cooling Systems
|
|

Laird offers 3 types of liquid heat exchanger systems (LCS). The standard cooling capacities ranging from 500W to 5kW. But also special solutions up to 40 kW cooling capacity will be developed and built. Standard configurations are either liquid or liquid-liquid systems air. All systems are suitable either for the operation with water, water with glycol (antifreeze) or oil.
Application examples:
- Medical imaging systems (eg: x-ray)
- Industrial and medical laser systems
- Digital printing, centrifuges
- Semiconductor manufacturing
- Series WL - water cooling-air
Water-cooled systems are designed to circulate water or mixture of water and glycol (antifreeze), and so to keep the coolant temperature close to the ambient temperature. The WL series are a reliable, compact liquid-air heat exchanger which can dissipate large amounts of heat with a circulating fluid circuit. The coolant is fed with a high pressure pump in the circuit to ensure a maximum flow rate. The heat is absorbed by a heat exchanger and submitted by fans leading manufacturer to the environment.
Available Types:
- WL 500 - 500W cooling capacity - 2.5 bar - 37x30x15cm
- WL 1000 - 1.000W cooling capacity - 6.0 bar - 33x29x30cm
- WL 1500 - 1.500W cooling capacity - 6.0 bar - 48x40x48cm
- WL 2000 - 2.000W cooling capacity - 6.7 bar - 30x30x50cm
- WL 3000 - 3.000W cooling capacity - 8.0 bar - 48x40x48cm
- WL 5000 - 5.000W cooling capacity - 7.0 bar - 48x40x48cm
- Series OL - oil-air
Oil-cooled systems are then used, if the temperature exceeds the heat source at the maximum operating temperature of refrigerants, water-based. Cooler of the OL series are reliable, compact liquid-air heat exchanger which can dissipate large amounts of heat with a circulating fluid circuit. The coolant is at a high-pressure pump in the circulation maintained in order to ensure a maximum flow rate. The heat is absorbed by a heat exchanger and fan submitted by leading manufacturers to the environment.
Available Types:
- OL 4500 - 4.500W cooling capacity - 9.0 bar - 75x35x65cm
- OL 15000 - 15.000W cooling capacity - 1.75 bar - 70x64x98cm
- Series WW and OW - liquid chillers
Liquid-liquid systems use water plant for thermal regulation of the hot side. This increases the cooling capacity and reduces maintenance. The WW-Series is suitable for operation with water, the OW series for operation with oil.
Available Types:
- WW 3001 - 3.000W cooling capacity - 6.7 bar - 45x27x40cm
- WW 5001 - 5.000W cooling capacity - 6.5 bar - 45x30x37cm
- OW 4002 - 4.000W cooling capacity - 9.0 bar - 62x35x55cm

WLK-Recirculating Chillers
|
|

The WLK series is a recirculating cooler on compressor base. The reliable performance is determined by the temperature control of the circulating water or water-glycol mixture of ethylene (antifreeze), in a liquid circuit achieved.
The heat from the cooling agent is delivered by means of permanent circulation compressor to the environment.
The device has an easy to use digital temperature controller and is housed in a sturdy metal housing. Standard cooling capacities ranging up to 3kW, also customized solutions up to 200kW can be realized.
Application examples:
- Medical imaging systems (eg: x-ray)
- Industrial and medical laser systems
- Digital printing, centrifuges
- Semiconductor manufacturing
Available Types:
- WLK 21 - 2.000W cooling capacity - 8.0 bar - 59x61x92cm
- WLK 31 - 3.000W cooling capacity - 6.7 bar - 59x61x92cm
