Water-Cooled Chiller

Compact Size

In relation to the power output, the dimensions of the chiller are designed to provide the most compact and easy-to-maintain machine possible. Each unit is supplied complete with the electrical control and operating panel.

Easy to Transport

Varimatik chillers are designed to be easily lifted and transported as a single unit using standard vehicles. They are delivered ready for "plug & play" installation.

Energy Savings

Varimatik is a green chiller. This means it is capable of reducing operating costs and CO₂ emissions.

Water-Cooled Chiller


In 1994, a large roasting company, seeking reliability and efficiency, contacted us to create a chiller capable of ensuring maximum reliability, cost-effectiveness, and environmental sustainability in the cooling system.

This is how Varimatik was born, our water-condensed ammonia chiller with an evaporative condenser.

Varimatik (single compressor) is a chiller with screw compressors available in three versions: water-condensed monoblock, with evaporative condenser, or with remote air condenser. It is available in an enclosed version for outdoor soundproofing, or indoor. The power, regulation, and control electrical panel is mounted directly on the machine.

Thanks to the integrated management of all system components, the machine continually assesses and adapts to load demands.

To date, we have installed more than 120 chillers of this type worldwide.

Why Choose Varimatik



Zeromatik is Zudek's accessory that allows any of our chillers to produce cold water consistently. The system optimally utilizes plate heat exchangers, where water is cooled to a temperature close to freezing. This is possible thanks to precise and controlled management of ammonia evaporation.

The Zeromatik system for cold water production can be installed in all Zudek solutions, including water-cooled systems, air-cooled systems, and water and ammonia absorption chillers.

Many dairy industry companies, where cold water is a critical element in the production process, have already installed this system.

But they are not the only ones! In fact, Zeromatik is the best solution for effectively managing various types of processes, such as vegetable cooling, carbonated beverage bottling, and activities in wineries.
