Rave Reviews

“The heater we purchased from Calco is used to warm CO2 so we can inert UST’s (underground storage tanks) before we put a camera inside the tank to do a visual inspection. It worked great and cut down the time by almost half of what it usually takes us to inert a UST. I’m sure this is not the usual way this heater is used, but it worked great and we will be using it on any future jobs we get!”
