Water-Cooled Chiller
Description
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.

Strengths
Ecological
Our water-condensed chillers use ammonia as the refrigerant fluid. Ammonia, besides being a natural gas, has a GWP (Global Warming Potential) and an ODP (Ozone Depletion Potential) of zero.
Sustainable
Our water-condensed chillers, thanks to their features, are green chillers as their efficiency and use of ammonia enable energy consumption reduction and CO2 emissions reduction.
Easy to Transport
The Varimatik chiller is designed to be easily lifted and transported using common means, in a monoblock version, delivered and ready for a “Plug & Play” installation.
Quiet
Varimatik can be placed in a soundproof cabin, allowing our machine to be extremely quiet when in operation.
Compact Size
In relation to the delivered power, the dimensions of the chiller are designed to provide the most compact and easily maintainable machine possible. Each Zudek machine is supplied complete with the electrical control and operating panel.
Customizable
All elements of our machine can be modified and customized based on the needs and requests of the customer. If necessary, all chillers can be designed and constructed in ATEX versions and provided with PED 97/23/CE certification and testing according to ISO 9001:2008.
24/7 Monitoring
Thanks to our Telematik system, we can remotely monitor the machine to analyze its proper operation and intervene promptly.
Zeromatik
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.
Strengths
Efficient
Zeromatik allows you to replace the ice storage tanks typically used for cold water production. This results in significant energy and operational cost savings.
Compact
Zeromatik is small in size, making it easy to integrate into existing systems
Versatile
Zeromatik is available for both water-cooled and air-cooled compression chillers, as well as absorption chillers. Moreover, it can be easily integrated into existing ammonia refrigeration systems.
Consistent
Zeromatik enables the production of chilled water at a constant temperature without interruptions. This system allows for continuous operation at the same temperature 24 hours a day.
Reliable
Custom-sized for the customer and thanks to Zudek's control logic, there is no risk of freezing.
