300GTSgreenthawTM

systemFor ground thaw & concrete cureapplicationsdesigned to operate in colder climates...aslow as -40°F (-40°C)

Unmatched temperature control The DRYAIR greenthawTM system gives youalmost perfect control over the temperatureof your concrete pour. By adjusting the ‘flow reverser controller’ tothe recommended schedule, every squarefoot of your concrete pour will receive thesame amount of heat. This means a uniformcuring pattern and less likelihood ofproblems caused by uneven curing.Dryair's ‘even heat’ approach to curing willalso reduce the risk of freezing.Large capacity heaterThe large 301,000 BTU heater provides youwith ample BTU’s maximizing heatexchanger capabilites even in the harshestcontidions. Unlike conventional systems, the HTF flowreversing system gives you the addedadvantage of laying out more hose withoutthe need of a second pump.

Outstanding combustionreliabilityDRYAIR's patented CEC system(combustion environment control system)pre-heats the combustion air and fuel toprovide the burner with an ideal combustionenvironment in the widest range of ambientconditions. Wide outside temperature swings don’t fazethe DRYAIR ‘300GTS greenthaw system’... ithums right along!Large hose reel capacityThe hose reel is capable of carrying a totalof 3000 ft. for more thawing or curingcapacity. Enclosed trailer offersconvenience and ease Dryair's enclosed design not only offers easeof operation and convenience, we alsocontinue to honor our tradition of excellentservice access to all components.

Uniform thaw =energy savings

The Dryair greenthawTM

system maximizes every ounceof the energy it uses bydirecting heat across the thawgrid in a systematic mannerthat results in a uniform thawpattern. Other systems use circulationloops that move fluid in onedirection only. The fluid, asheat transfer occurs, will cooldown as much as 45% as itmoves towards the end of theloop. This will result in anuneven thaw pattern.Therefore, while ground underthe warm end continues to beheated, energy is wasted wellafter it has been thawed due tothe colder end of the loopfalling behind by as much as75%. This forces you to thawfor several days longer...needlessly costing you extratime and fuel.Dryair's ‘patented’ greenthawTM

system maximizes your costlyenergy by reversing fluid flowon a selected schedule. This means that every squarefoot of ground sees the sameamount of energy giving youan almost perfect thawpattern... and more importantly,saving you valuable time andreducing energy requirements.
