Engine/spindle supply (cooling water recooler)
In a plug-in-ready design
The refrigerating machine is a compact, air-cooled liquid cooler in a painted, galvanized steel sheet frame housing with screwed-on, removable cladding sheets on all four sides. Prefabricated piped and wired. All components and electrical equipment comply with the latest technical standards and meet current safety regulations such as EN 60204und EN 378.
Quality and performance characteristics
· Overload protection for pump motor, compressor motor and fan motor
· Copper tube coaxial evaporator with robust immersion
· Air-cooled condenser with large lamella spacing
· Slow-running axial fan
· Inspection glass with humidity indicator, filter dryer, refrigerant and oil filling high- and low-pressure switches for protecting the components of the refrigeration circuit
· Electrical or electronic control panels, whether or not incorporating a single-shaft or multi-shaft electrical circuit, with a combined output voltage of >= 1 V Main switch and electronic controller as a microprocessor controlled control and regulation unit with a keyboard with simultaneous indication of set and actual temperature values, with functional and fault indications
· Pressureless, large stainless steel tank with viewing opening, venting and venting openings and shut-off emptying. With condensation water insulation of the tank side walls and the bottom (min. medium temp). 12°C at ambient temperature 35°C 50% r.F.
· Tank with optimized flow guidance of the return flow medium via the evaporator
· Operating pump as a low-noise centrifugal pump with stainless steel internals and jackets and connection housings of cast iron
· Electrical level monitoring of the tank as dry running protection for the pump
· Chlorine-free refrigerant R 513A (low GWP) without ozone-depleting effect with high operational safety at high ambient temperatures and good EER values
· Embodiment on stable, steerable transport rollers with locking levers
