with two-stage power-control
without built-in accumulator
The KWL 440-780 devices are particularly noiseless, air-cooled coldwater generators for outdoor installation with integrated “low-noise fan control” for the power range between 43.5 and 77.7 kW.
The self-supporting housing made from powder-coated steel sheet has removable panels. This means that all components can be conveniently accessed for maintenance. The standard design is supplied without accumulator, circulation pump and expansion tank, and can therefore be optimally adapted to the local plant requirements.
Compact design and maintenance-friendly device structure
Powder-coated housing and condenser protective grille
Comprehensive set of accessories available
The standard equipment
A refrigeration circuit with safety components, 2 scroll compressors and stainless steel panel heat exchanger
Master switch and electrical phase monitoring
Centralised alarm contact
Electrical release contact
An easily operable from outside, microprocessor controlled control system with two-stage power control
Low-noise fan control system for particularly low noise emission
The control system
The control of the cold-water generator is undertaken by means of an internal controller or via a convenient wired remote control.
The user-friendly designed controller enables the entry of the desired water temperature and all additional functions.
The clearly structured display is subdivided into value and functional displays and enables a clear functional analysis of the device for the operator.
A standard release contact enables device operation to be e.g. suspended for a period of time, in order to reduce operating costs to a minimum.
