New DrainMinor C (Combi Oven Pump) Creates considerable interest at HRC Catering Exhibition

R-TEC Service & Innovation Ltd. (previously known as Rational Technical Services UK Ltd.) demonstrated its Combi Oven equipment to commercial kitchen operators at the recent HRC ExCel London Exhibition. On the stand was a working demo of a Rational Combi Oven and the New DrainMajor C (Combi Oven Pump) manufactured by partner Pump Technology Ltd.

This proved a focal point for Combi Oven manufactures, installers, maintenance engineers and users alike. Potential users were shown a number of significant advantages that this combi oven drainage pump offered.

Very noticeable when viewing the exhibition demonstration tank with its clear side window was the large, triangular, low-level float attached to the pump by a rigid arm, external to the pump casing. Because of the design of this float system the unit can cope with an exceptional quantity of grease, fat and food particles before the reliable start/stop operation of the pump is affected.

The triangular low-level float also means that inlet heights can be just 70mm from base to centreline, giving the appropriate inlet requirement for wall or central island Combi Ovens.

The build quality of the submersible wastewater pump was also a discussion point, with the mechanical shaft seal arrangement between pump impeller and motor winding generally agreed as an advantage over a common lip seal/diaphragm arrangement, especially considering the hot wastewater temperatures and potential grease which these units have to handle.

It can be connected to multiple ovens or oven and sink combinations. Also, multiple inlet connections can be cut onsite directly into the rigid Polyethylene tank without the need to manifold inlets outside of the tank and then feed into it via a single inlet. This means that the installation footprint is just the size of the compact tank and potential leaks from knocked manifold piping and joints are eliminated.

It looks like the New DrainMinor C is a winner and will soon be featuring in combi oven installations everywhere.
