The new range of heaterSteam immerse heater humidifiers includes models producing from 2 to 60 kg/h of steam, and can operate on drinking water or demineralised water. heaterSteam features exclusive technological solutions, such as the electric heaters embedded in corrosion-proof aluminium alloy casting with a large heat exchange surface, and built-in temperature sensors to prevent overheating. For each model there are two variants: basic and “full option”. The full option units have heat insulation around the boiler for maximum energy savings, and Teflon coated heating elements to facilitate the separation of lime scale. The heaterSteam range is available with 3 types of control: H, modulating with built-in controller (from active humidity probe); T, with temperature control (from external probe); C, for simple ON/OFF control . The models from 2 to 10 KG/h have a cylindrical stainless steel boiler, which is easy to remove for cleaning; The larger models, from...

Naturally there is also a DIN rail version of ir33, radically upgraded from its predecessor. In this format, ir33 is completely compatible with the panel version in terms of both software and functions. The hardware features are very powerful: it can control compressors with ratings up to 2 Hp and manage the defrost heater with a 16 A relay. The top-of-the-range version has 5 relay outputs, while all models come as a standard with 2 control probes and 3 digital inputs that can be configured as probes. Accessories:   Infrared remote control : This new accessory is used to directly access the main functions and configuration parameters and to program ir33 from a distance, with a group of buttons that represent n exact copy of the instrument keypad.   RTC : this accessory is used to record detailed data with precision, and set the defrost function according to the real time (and not at intervals, as is usually the case). The RTC ensures that ir33 conforms with th...

Ir33 can operate not only in stand-alone mode, but also in a local network, using an external control (synchroniser), with the advantage of not having to lay additional wiring. This characteristic is particularly useful and effective in the case of applications with multiplexed cabinets, where all the operations of the installation need to be managed in a synchronised manner, above all as regards the defrosts. The defrosts start at the same time on all the sections, and then end independently, in relation to the status of the different sections. When the defrost is completed, the subsequent refrigeration phase is started in synch on all sections. The local network can be used to centralise and synchronise not only the defrosts, but all the functions, on a single display. This means that when pressing the light button, for example, the command is transferred via serial connection to all the boards, which activate the light at the same time. The same applies...

The famous ir32 series of controllers has given rise to the new generation of controllers for refrigeration! The new ir33 includes: infrared remote control, programming key, repeater display, high efficiency LED display, HACCP function, clock, RS485 serial port, defrost management on a second evaporator, all without sacrificing the 4 relay outputs and the 115 to 230 Vac switching power supply! All this in the same dimension as the current ir32! ir33 also manages smart defrosts, resulting in energy savings for the entire intallation. IP65 is guaranteed: the innovative technology used by CAREL to mould the plastic parts allows the protection gasket to be integrated directly into the front panel. In models with an internal clock, HACCP management is standard: this guarantees the temperature control of the foodstuffs stored, in compliance with the requirements of the HACCP system. The parameters are set directly on the instrument: the time and temperature limits envisaged b...
