Efficient Cooling Technology

The TECO TK Series uses high-performance compressor technology together with a titanium heat exchanger to deliver high cooling performance with low energy consumption.

The combination of technologies used throughout the range is designed to achieve an excellent coefficient of performance (COP) while reducing operating noise.

Precise Digital Thermostat

The digital thermostat provides intuitive control and accurate temperature monitoring.

• Temperature setting range: 5°C–30°C (41°F–86°F)
• Temperature resolution: 0.1°C / 1°F
• Maximum temperature differential: 0.5°C / 0.5°F
• Temperature display in °C or °F
• Security alarms

Compact & Practical Design

The innovative TK Series design combines a solid structure with compact dimensions. The structure is designed to provide protection against rust, while the compact footprint makes the chillers suitable for installations where available space is limited.
