Get in touch with our Sub Zero Chillers experts

In addition to the LTZ- -25 series with a temperature control range of -25℃
to -30℃, LNEYA Sub-Zero Refrigeration can also achieve the following:
 – Standard Temperature Industrial Chillers (5~35℃)  
  This is the most widely used temperature control range in the industry. However, if a more precise temperature of 3℃ is required, this should be specified when designing the industrial chiller system.
 Medium-Temperature Industrial Chillers (-20~0℃)
 

Low-Temperature Industrial Chillers (as low as -40℃)  
  We offer industrial chillers that can reach temperatures as low as -40℃
, typically used in the chemical, pharmaceutical, and other industries for cooling reactors or recovering condensed materials.
 
 Ultra-Low Temperature Industrial Chillers (as low as -120℃)  
  Our ultra-low temperature chillers provide cooling fluids as low as -120℃. These are referred to as deep low-temperature industrial chillers and use a binary cascade or ternary cascade refrigeration system, also known as cascade industrial chillers.
 
As you can see, industrial chillers offer a very wide temperature control range, helping solve various sub-zero challenges!。

Cascade refrigeration technology
Secondary supercooling technology
Frequency conversion technology
High and low temperature rapid heating and cooling technology

LNEYA Sub-Zero Chillers operate using a closed-loop system that circulates refrigerant, typically a mixture of ethylene glycol/ethylene glycol water solution. The refrigerant absorbs heat from the cooling process or equipment, then flows through a heat exchanger. In the heat exchanger, the heat is transferred to the cooling water, which is then dissipated through a cooling tower or other heat dissipation methods.

The cooled refrigerant is then recycled back into the process, maintaining the required temperature. This continuous loop ensures consistent cooling, providing a stable temperature for the system or application.

This process is efficient and effective for applications requiring precise, low-temperature control.
