The ground thawing system employs an array of 5/8″ hoses laid across sections of frozen soil or concrete that is setting. These hoses act as channels for circulating a warm solution of propylene glycol. To improve its thawing capability, the soil is covered with a polyvapor barrier, and thermal blankets are used to cover the hoses, thereby creating a controlled heating environment that pushes heat directly into the soil.
This system uses dual coil heaters to heat the propylene glycol mixture in a tank to 180 degrees Fahrenheit. The mixture is then pumped through the hose network, aiding in the defrosting of the ground. After circulation, the solution returns to the tank to be reheated, maintaining a consistent heating cycle.
The Portable Glycol Ground Heater offers a flexible and efficient approach to address the issue of frozen soil, capable of thawing up to twelve inches of soil daily. It plays a vital role in ensuring the proper curing of concrete in colder weather and helps maintain the necessary temperatures for ongoing construction work. With its portability, this heater is an essential tool for various construction projects, especially in conditions where winter weather significantly impacts project schedules and success.
