LBX Oil to Water


LBX - Liquid to Liquid - Oil to Water

AB45 Oil Air X-Ray Cooling Sytem B Grnd

Whilst the LBX range of oil to water coolers have been specially adapted for x-ray tube cooling applications, they can also be used for cooling other applications where chilled house water is available.

The LBX x-ray tube cooling systems utilise chilled house water to remove process heat from the oil coolant via a water to oil exchanger.  Our x-ray tube cooling systems provide process coolant at constant temperature and pressure thus ensuring your x-ray tube performs at optimum performance.

The LBX range of x-ray tube cooling units are compact, self-contained and capable of providing oil at nominally 5 to 10 ⁰C above the chilled house water temperature and at constant pressure. They incorporate a high pressure oil pump, stainless steel coolant reservoir, temperature controller and a thermostatically controlled modulating valve to control the flow of house water. Standard safety interlocks designed to protect the x-ray tube, include coolant over temperature, low level and low flow, all communicated via volt free contacts, which are monitored by the customer.

Additional system protection is provided via a unique slow start function whereby the pump pressure is limited on cold startup to protect the x-ray tube from over pressure.

Standard units can be adapted further to suit individual requirements.
