Variable Speed Refrigeration Dryers
CD-VS Series
A Next Generation Energy Saving Variable Speed Refrigeration Dryer
Cycling & Non-Cycling
Refrigeration Dryers
Benefits
First-class air treatment efficiency
The low environmental impact R513A refrigerant gas combined with a variable speed operation is the height of technological evolution and maximises respect for the environment. By using inverters, it is possible to modulate the electrical power input by the scroll compressor and fans according to the thermal load required by the user.
ADVANTAGES:
Greater environmental friendliness
Reduced running cost
Optimised consumption and performance under all load conditions
Many testing hours in our R& D laboratories have confirmed the reliability, robustness and performance of the new CD-VS range, made of high quality materials, mechanical and electronic components from leading international brands in the industrial refrigeration sector.
Eco-friendly R513A refrigerant
The CD-VS refrigeration dryer series uses the environmentally friendly R513A refrigerant gas with low GWP, which is non-toxic and non-flammable, and makes it possible to install CD-VS units indoors. The CD-VS dryers wide operating limits meet the most diverse industrial demands.
Design
Variable speed
Variable speed dryers, using inverter technology for compressor and fans, can adapt their energy consumption according to the thermal load applied, and adjust the refrigerant flow rate to the ALU-DRY heat exchanger. With the new DMC55 controller and electronic EHGBV hot gas bypass valve, the user can choose between Cycling or No-Cycling operation for extremely low heat loads.
DMC55 Electronic Controller
The CD-VS series is equipped with the DMC55 electronic controller, which has an intuitive user interface with its 4.3” capacitive touch screen display and multiple functions. The controller constantly monitors the operating pressure and temperature values and adjusts the compressor and fan speeds. This ensures an extremely stable dew-point under all operating conditions.
THE NEW MAIN FUNCTIONS INTRODUCED ARE:
Weekly on-off programming
Display of instantaneous electrical power input
Display of spare-parts list
Dryer management via Modbus RS485 RTU communication (Industry 4.0 ready)
Electronic hot gas by-pass Valve – EHGBV
The electronic hot gas bypass valve EHGBV directly controlled by the DMC55, introduced a No-cycling mode. This function allows maximum performance even in conditions of low thermal loads: the compressor, in this condition, never shuts down, remaining at minimum speed and delegating the cooling capacity control to the EHGBV, which guarantees continuous and stable regulation.
Five operating modes
The CD-VS range is equipped with intelligent/automatic management of five operating modes, which can be set directly from the controller display:

Standard
ECO
ECO Plus
