Ammonia Absorption Chiller
The cold without electricity
Absorbers harness heat sources of all kinds to generate refrigeration energy. They recover hot process fluids, waste industrial gases, and cogeneration by-products.
Low Maintenance
Being an "oil-free" system with a single pump, maintenance requirements are minimized, further reducing plant operation costs. Additionally, with our Telematics system, absorbers are remotely monitored. Our technicians oversee all machine parameters in real-time.
Environmentally Friendly
Ammonia is a naturally occurring gas that does not pollute. It is the best refrigerant available on the market. Our highly advanced systems allow its use in very low quantities with virtually zero environmental impact.
Built to Last
The absorbers are designed and built to withstand the most extreme conditions for many decades.
The invention of hot water
Typically, cogeneration plants fall under the CAR - Cogeneration High Efficiency - parameters thanks to the use of the absorber alone. The new trigeneration plants are designed for higher efficiency and lower electricity consumption. They simultaneously produce all the energy a facility needs: electrical, thermal, and refrigeration.
Description
Albert Einstein presented in 1930 for the first time a no-moving-parts absorption refrigerator that required only a heat source to operate.
More than sixty years later, we at Zudek embraced and developed this refrigeration system, using a water and ammonia solution (ammonium hydrate), making it one of our strengths.
Enermatik is an ammonia absorption chiller that generates refrigeration power from thermal energy.
Features

Strengths
Eco-friendly
Our chillers use only ammonia as a refrigerant. Ammonia, which is a natural gas, is the only refrigerant with a GWP (Global Warming Potential) and ODP (Ozone Depletion Potential) equal to zero.
High performances
Ammonia has the highest refrigeration efficiency of any refrigerant, allowing for greater efficiency compared to other refrigerants.
Maximum efficiency
When combined with a cogenerator, Enermatik falls into the High-Efficiency Cogeneration (C.A.R.) category, achieving efficiencies exceeding 80%.
Energy Recovery
Enermatik allows us to generate cooling power directly from waste and /or thermal recoveries.
Low Maintenance
Constructed from galvanized carbon steel, Enermatik is both robust and durable. It operates statically with only one moving pump, minimizing maintenance requirements.
Low Electricity Consumption
Each Enermatik unit produces 20 kW of cooling with just 1 kW of electrical energy.
Ease of Installation
Transport, installation, fluid charging, and startup in just 3 days.
Certifications
Enermatik is available with ATEX certification, according to the PED codes, and all temperature values can be MID certified (Measure Instruments Directive) upon customer request.
24 / 7 Monitoring
Thanks to our Telematik system, we are able to remotely monitor the machine to analyze its proper operation and promptly intervene when necessary.
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.
