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...

The EVD evolution series of controllers for electronic valves is the latest step in the development of the famous CAREL drivers for superheat control. Compared to the standard EVD, this instruments adds advanced functions and a new user interface that makes it even easier to use and configure. The new TWIN version can independently control two electronic expansion valves, and represents the ideal solution for two circuit units or different control function (i.e. superheat and hot gas bypass). A new graphic display and a simple programming procedure allow the controller to be started by selecting just 4 parameters:   - refrigerant used; - model of valve; - type of pressure probe; - application (chiller, display, cabinet, etc.), selected from the multiple choice menus. EVD evolution is complete with LEDs for controlling the main functions, and can house a removal LCD display for the configuration and monitoring of all the variable. EVD evolution can be...

Carel electronic expansion valves E2V with proportional modulation and excellent technical and functional characteristics, allow an efficient control of refrigeration and air-conditioning units , and consistent energy saving performance. The flow of refrigerant is modulated by nozzle coupled to a torpedo shaped aperture, measuring more than 15 mm long, over a wide operating range. The internal mechanism is fitted on a calibrated spring with ball bearings and guarantees a stable and reliable regulation reducing the risk of failures. E2V is completely manufactured using laser-welding techniques on high-quality materials (AISI 316L), as well as technopolymers. Carel has paid special attention to the smallest details in designing E2V to ensure very high reliability for operations up to 35 bars of differential pressure and up to 45 bars of absolute pressure. Other features include exclusive axial motion of the nozzle aperture and seal gasket in the closing position. By install...

The Carel rTM monitoring system, is used to monitor temperature, humidity, light intensity and pulse counters from energy meters modules, in combination with Carel, supervisory systems or programmable controllers with special software. Benefits Ideal for retrofits on existing systems, being easy to install: -    No electrical connections required; -    Flexible layout in the event of structural modifications; -    Simple installation and maintenance; -    Existing controllers do not need to be replaced, as the system is completely independent and can be integrated into any installation; -    Simplifies monitoring of the installation (including over remote connections). In the event of alarms, operating status can be notified via SMS, email, FAX; -    Supervisory systems can be customised reports and data log files; Composition -    Battery or mains powered sensors for measurin...
