A28 Mechanical thermostats

Controls are compact with fixed differential per stage and (on most models) adjustable differential between stages. Liquid filled element provides wide range, constant differential, no influence from barometric pressure and is cross-ambient. All standard IP30 enclosure models have a universal way of adjustment. For this purpose a knob and sealing cap are enclosed.

• Liquid filled sensing element, so no cross ambient temperature problems
• Dust tight PENN^® switch prevents pollution of the contacts by electrostatic influences
• IP65 protection class models available
• Front adjustment
• Suited to be used in the presence of A2L refrigerants
