Description
The “ EWHT1800LX ” controller in the new Coldface series is a device for applications with double compartment cells which
provides control of both temperature and relative humidity .
It is suited to the control of commercial and industrial cold cells and, thanks to the wide number of outputs available,
provides control of all associated functions, including lights, alarms , and condensation fans ., ventilation fans , stratification
fans , humidification/dehumidification and heating .
The curing/ageing/storing cycle consists of 1 program with 8 climate profiles ; completely configurable by the user, the
combined control of temperature and relative humidity as well as defrosting makes Coldface the best electronic solution
for curing and keeping all food and consumable products.
The graphic interface features a backlit LCD display .
Menus are user-friendly and parameters can be easily viewed thanks to the large surface area of the display itself.
The Datalogger function, standard on the device, , logs, keeps and stores all temperatures and alarms ,
thus ensuring quality and reliability of the products, with special reference to HACCP standards.
The HACCP function sets, maintains and memorises temperature measurements and any associated alarms , ensuring the
quality and hygiene of stored products.
The product is equipped with an optional RS-485 serial port, which enables connection to TelevisSystem and ModBUS
without the need for external accessories .
The 95 to 240V~ switching power supply ensures usability in any application.
