Envirolok ™ Motor Rewind Service…Dedicated to Quality…
The Envirolok rewind system is designed to meet the uncommon demands of centrifugal chillers. High performance
materials and special winding techniques result in a rewind that can withstand the harshest operating conditions. PLUS…
with an Envirolok motor rewind you’re assured of compatibility…with the refrigerant you’re using today, or the one you’ll need
tomorrow. To meet your requirements, two Envirolok systems are available for all hermetic motors – regardless of brand.
Envirolok LV for low voltage random-wound motors.
Envirolok HV for high voltage form-wound motors.
Mechanical Strength
Extra Voltage & Surge
Protection
Envirolok LV. Special stator slot
insulation technique prevents failures
due to loose wires.
Envirolok HV. Coil heads blocked
and braced with compatible materials,
resulting in negligible coil movement.
Insulation Integrity
Envirolok LV. Special magnet wire,
phase and group insulation provide
added surge capacity.
Envirolok HV. A combination of
special magnet wire, ground and
armor insulating tapes assures high
electrical strength.
Envirolok LV. Special epoxy varnish
system prevents refrigerants from
damaging motor insulation.
Envirolok HV. Stators are vacuum
pressure impregnated (VPI) to
transform coils into a solid, rugged
mass – free of voids; excellent heat
dissipation; superior resistance to
solvent effects of newer refrigerants.
