STM - Water Chiller

• Cooling process water for dough mixers and other food preparation machinery.
• Maintaining precise temperatures in fermentation vessels and storage tanks for beverages.
• Rapid chilling of cooked foods to extend shelf life and meet food safety standards.
• Temperature control for chocolate tempering and confectionery production.
• Cooling jacketed vessels used in dairy processing for milk and cheese production.

Typical cooling capacity

For this class of equipment, capacities commonly range from 5 kW to 100 kW, depending on the specific application and required temperature delta.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V/50Hz, with varying amperage requirements based on capacity.

Refrigerant type

Modern chillers commonly utilise HFC or HFO refrigerants, selected for their efficiency and environmental profile.

Temperature range

Process water chillers typically deliver chilled water between +5°C and +20°C, though some specialised units can go lower.

Footprint

The physical dimensions vary significantly; compact units may be under 1m², while larger industrial chillers can occupy several square metres.

Pump type

Commonly features an integrated centrifugal pump for circulating the chilled water to the process.

• What is the primary function of a water chiller in food processing?

  A water chiller provides a continuous supply of precisely temperature-controlled chilled water, which is essential for cooling various food processing operations and maintaining product quality and safety.

• How do I determine the correct chiller capacity for my needs?

• What maintenance is typically required for a water chiller?

• Are there different types of water chillers?

• What are the common safety features on a food-grade water chiller?

Chillers and recirculating coolers hold strong reputation in laboratory and biotech sectors for temperature stability and process reliability. Buyers typically prioritise checking refrigeration system condition, pump functionality, and temperature control accuracy when purchasing used units. Industry sentiment favours models with robust construction and established service records. Common strengths include consistent cooling performance, energy efficiency relative to age, and durability when properly maintained. Verification of calibration history and cooling capacity specifications remains essential before purchase to ensure suitability for sensitive applications.
