To realize state-of-the-art plants are essential advanced technologies and reliable components.
The Company uses the strong experience of its technical staff to design the new high-efficiency refrigeration plants always searching for the best production of components in the international markets in terms of materials quality, performances and efficiency.
One of Zanotti's leading products is the refrigeration rack system, which can be cataloged in different units depending on the size, is one of the latest products in temperature control field.
In addition to multicompressor refrigeration system, the Company offers a range of components in support of its plants.
- Ice machines (cubes or flakes)
- Blast chillers
- Freezing tunnels
- Special liquid coolers
- Direct expansion or intermediate fluid cooling batteries
-
RCHA - ammonia liquid cooler with reciprocating compressors
Refrigeration capacity from 70 to 700 kW
Advanced Industrial Construction
- New generation units
- Designed for high working pressure
- Pressure and vacuum tested units
- Construction codes PED, SVTI, ASME and other on request
- Stainless steel or titanium plates evaporators and condensers
- Automatic oil recovery system
Low ammonia charge
- Thanks to the use of plate heat exchangers, it is possible to achieve very high cooling capacities with a minimum filling of ammonia in the circuit. This type of chillers satisfies the requirement of environmental safety and compatibility and permits to simplify the steps required by the Authorities for the installation and the use of ammonia plants.
- Easy installation
- The chillers are delivered complete preassembled, wired and insulated. The only activities required on site are the power supply to the switchboards and the connection to the solution circuit and cooling media circuit if any.
Low operating costs
- Reduced energy consumption
- Step capacity control which adjusts the refrigerating capacity according to the demand
- Possibility of infinite capacity control by means of inverter (optional)
-
