The capillary tube has been used as a refrigerant metering device for many decades. Many HVACR manufacturers are still successfully employing capillary tube metering devices in their latest equipment.

Capillary tubes are generally used as the metering device on small, fractional-horsepower refrigeration systems. Charging these systems with refrigerant requires a different procedure than those ...

Capillary tube refrigeration systems are integral components in compact refrigeration and air-conditioning units. These systems utilise a narrow, precisely dimensioned tube to regulate the flow of ...

How can the Vapochill LS unit get so darn cold?! In essence, there are four key mechanisms on the go in a phase change system. These parts are connected in a closed loop by tubing, this loop is filled ...
