HTSL series low temperature screw chiller is widely adopted in manufacturing process in industries such as

non-ferrous smelting / chemical / pharmaceutical / petroleum chemistry / grain and oil / food and beverage / mechanical / electric / air separation

Food Processing

To guarantee the safety and consistent quality of frozen foods, food processing companies need low-temperature cooling day in and day out. Our low-temperature screw chillers have been put to the test in a range of food-related applications, including:

  • Fast freezing of prepared food and meals
  • Storage of food ingredients before use
  • As part of disinfecting and antibacterial cleaning

Medical Processing

Certain medical fabrication processes and storage requires reliable cooling to guarantee safety and effectiveness. When cooling failure isn’t an option, you need a low-temperature scroll chiller you can count on for:

  • Transforming various medical ingredients and compounds
  • Manufacturing highly sensitive medicines
  • Storage of medicines and human tissues for surgery
  • Testing of new drugs and procedures in extreme cold conditions

Product and Material Testing

Many types of clothing, materials and equipment need to be tested to -35°C temperatures. Our low-temperature industrial scroll chillers can be used for a wide range of testing applications, such as:

  • Automotive and transport equipment verification
  • Fabric and cloth cold temperature resistance and protection
  • Plastic, rubber and metal strength at freezing temperatures
  • Cold temperature performance of coolants, oils and fluids



Dependable, versatile, high-efficiency cooling.

HERO-TECH chillers deliver value to a wide variety of applications with enhanced energy-efficiency options.
