Winter Construction Specialties has replaced their stock of Thawzall ground heating units for the Green Power Technology’s Fusion 300. Winter Construction Specialties will still provide parts and service for our existing Thawzall machines. We have several Thawzall units for sale in our used equipment section. Winter Construction Specialties has moved to the GPT Fusion 300 to focus on a multi-zone control curing system for bridge deck curing. The Fusion 300 can manage and adjust 6, 700 foot zones independently to allow each zone to maintain a different temperature. Specs will no longer be posted for our units except for general specs for used equipment per each machine.
