Everything you need to know about AHT KALEA Freeze SPI


KALEA Freeze SPI devices are already equipped with the necessary piping and flow control valve from the factory, allowing for quick installation through multiplex connections. With the Inbox technology, in the event of maintenance or servicing, there is no need to remove the products, as the remaining refrigeration circuit takes over the operation. This ensures convenience and uninterrupted operation during maintenance or service procedures.


The waste heat generated by the freezer cabinet can be utilized for heating the storage area or other business sections. The included piping on the refrigeration shelf allows the waste heat to be directed to the external pump station and condenser. This eliminates the need for a separate machinery room, resulting in space and cost savings.


The multi-circuit technology (<150 g R290 per circuit) in KALEA FREEZE SPI makes it more energy-efficient and reduces the risk of failure.
The number of circuits varies based on the number of doors:
5 doors = 3 circuits
4 doors = 2 circuits
3 doors = 2 circuits
2 doors = 1 circuit

The automatic defrosting feature is available in all temperature ranges.

KALEA Freeze SPI Highlights


Thanks to its semi plug-in installation, KALEA FREEZE SPI is immediately ready for use. It impresses with optimal space efficiency, thanks to its slim design with depths of 84 and 99 cm. KALEA FREEZE SPI is available as both a line unit, stand alone and a end unit. It features a condensate water drain that connects to the existing building's condensate water drain. As all products in the KALEA family (Chill & Freeze) share a consistent design, refrigeration and freezer devices can be installed side by side, creating a cohesive visual display.
KALEA FREEZE SPI models operate with a hermetic and sealed cooling system, minimizing the risk of leakage. All units are approved at the highest safety level by VDE (Association for Electrical, Electronic & Information Technologies). Additionally, they use the environmentally safe and natural refrigerant propane (R290), making them particularly eco-friendly.
With our Active Monitoring System (AMS), we detect issues before you even notice them. The AMS is a crucial add-on to all AHT products, making store management and monitoring of AHT refrigeration units significantly easier for you. Our devices are also compatible with other systems, enhancing their versatility.
KALEA FREEZE SPI offers optimal product visibility thanks to its anti-fog doors. The brilliant LED lights in the vertical bars, available in different colors (5000K, 6500K), provide excellent product presentation. The daily automatic defrosting ensures optimal operation. Particularly noteworthy are the numerous customization options, including end glass walls, bumper design, interior fittings, and more.
