Ex certified couplings are heat and humidity tolerant
09 July 2009
Couplings designed specifically for hot and humid environments have been introduced by Rexnord. They are available for both close-coupled and spacer applications.
They are therefore suitable for use in the most demanding of conditions.
In addition to being heat and humidity tolerant these Rexnord couplings, called Omega E HSU and ES HSU, are also ‘EX’ certified. They are therefore suitable for use in the most demanding of conditions.
Combined with these characteristics, these couplings offer all the advantages of the company’s standard split elastomer ‘flex’ element design. These include easy installation, replace-in-place capability and reduced inventory levels because of the common components employed across the company’s coupling product range.
Torque ratings for the OMEGA E HSU close-couple design range from 22Nm to 38,400Nm with high torsional stiffness up to 4J/kgm (280m/kg). For the ES HSU couplings the figures are 22Nm to 4,460Nm and 1.14K/kgm (82m/kg).
