Rittal 3364100 – Frequently Asked Questions
1) Which Rittal part number do I order for 2049 BTU versus 3412 BTU cooling?
Two capacities are offered on the Rittal air/water heat exchanger: MPN 3214100 at 2049 BTU and MPN 3364100 at 3412 BTU. Both are the 230V, 1~, 50/60Hz version with copper/brass (Cu/CuZn) water-carrying parts. Size to the enclosure's actual heat load, not to the cabinet size.
2) Can I mount this Rittal air/water heat exchanger inside the enclosure instead of on the outside?
Both. The unit supports external mounting or full internal mounting, with flexible water connection options so the supply and return can be routed to suit the panel layout. A drilling template ships with it along with sealing and assembly components, and the unit arrives wired ready for connection.
3) Will an IP55 / UL Type 1 heat exchanger keep my washdown enclosure sealed?
The housing is rated IP55 to EN 60529 and IEC 60529, with a UL Type 1 NEMA rating. IP55 covers dust and low-pressure water jets, but UL Type 1 is indoor, general purpose only. For hosedown or outdoor duty you need a Type 4/4X rated climate control unit instead, not this one.
4) What water temperature and pressure does the Rittal 3214100 heat exchanger need?
Water inlet temperature must be between 1 and 30 degrees C, and permissible operating pressure is given as 110 bar. Cooling medium is plain water. Ambient/operating temperature range is 1 to 70 degrees C and the unit runs at 100 percent duty cycle, so it can cool continuously rather than cycling.
5) Does this Rittal unit come with its own thermostat or do I need a separate controller?
Control is built in. An internal thermostat with a change-over contact and 16A switching load adjusts from +20 to +60 degrees C, factory set at +35. It drives a thermostat-controlled solenoid valve with a 20 to 55 degrees C setting range, so the water flow is modulated without any external controller.
6) What circuit protection does the 230V Rittal air/water heat exchanger require?
Pre-fuse the supply with a 2A miniature circuit-breaker or fuse. Supply is 230V single phase, 50Hz or 60Hz. On a 60Hz North American job that means a 230V single-phase feed, not 120V, so plan the panel circuit accordingly.
7) Why choose an air/water heat exchanger over a standard enclosure air conditioner?
An air/water exchanger has no compressor or refrigerant in the enclosure; it rejects heat into a chilled or process water loop, which is why it holds a 100 percent duty cycle and works in hot ambients up to 70 degrees C where an air-cooled A/C struggles. It only makes sense where you already have a water supply between 1 and 30 degrees C. No water loop on site, pick a refrigerant-based cooling unit instead.
8) Will the copper/brass version hold up in a plant with aggressive process water?
Water-carrying parts are copper/brass (Cu/CuZn), chosen for corrosion resistance in industrial water loops. That is the standard build, not the stainless option, so it suits treated or chilled water rather than chemically aggressive or saline media. Housing finish is RAL 7035, the usual light grey that matches Rittal enclosures.
