Demaco Subcooler

It’s all about Cryogenius.

 
subcooler

In most cryogenic infrastructures, some evaporation of liquid gas occurs. This results in a mixture of gas and liquid, which is not favorable for the infrastructure’s functionality, capacity, and operation.

Quality improvement products are widely used in cryogenics for the discharge of vaporized gases. For example, a phase separator, degasser, or a subcooler.

The Demaco subcooler is used to cool liquefied gas to prevent gas from forming in the pipes during operation. This is done by cooling the contents of the subcooler through a heat exchanger until the outgoing liquid has a lower temperature than the natural boiling point at absolute working pressure. In doing so, we make clever use of the natural temperature difference between liquid gases at different pressures.

In the subcooler, the pressurized liquid gas passes through a heat exchanger. This cutting-edge heat exchange process removes any evaporated gas bubbles from the liquid, resulting in pure, high-quality liquid gas.

A subcooler is constructed from modular building elements and assembled into a single vacuum insulated unit. This can be supplemented, if desired, with a temperature sensor for distant monitoring.

Specifications

The Demaco subcooler is made of stainless steel and comes in three standard capacity models with a cooling capacity of 0-500, 0-1500, and 0-3500 Kg/h. If required, we can also produce subcoolers with different cooling capacities.

Our basic subcoolers are all equipped with control valves regulating the cooling operation. This enables stable management of the out-flow.

Subcooler application

Typically, the subcooler is used in systems where a stable temperature is essential for process control and where a liquid is used as a refrigerant. In addition, a subcooler prevents temperature problems by regularly topping up the buffer and storage tanks. Especially in the food industry, aluminum profile extrusion industry, the electronics industry, and the space industry, subcoolers are commonly used.

For example, in the food industry, this practical product is used to control products’ cooling. In the electronics industry, the subcooler is used to test new electronic chips at different temperatures. In the space industry, the subcooler is used to supply subcooled liquid gases, such as nitrogen, oxygen, hydrogen, in test chambers or for the supply of rocket engines.

Accessory products

For correct operation, the subcooler should be combined with a level sensor and level controller. Optionally, a PT100 temperature sensor can be integrated into the subcooler.

Do you want to know more about our level sensor and level controller? Then take a look at our Level Sensor and Level Controller pages or download the Level Sensor or Level Controller product sheet.

The subcooler is always part of a complete vacuum insulated cryogenic pipe system. We supply both rigid and flexible transfer lines for proper integration, always using the highest quality couplings.
