Do you need to adjust the glycol concentration in your HVAC system? Houghton Chemical offers Freeze Point Adjustment Services. A multi-compartment truck arrives at your job site. Our driver hooks up to the glycol system and drains the low concentration glycol into a truck compartment. Concentrated inhibited glycol is then pumped into the system from a separate truck compartment. This process boosts system concentration to the desired freeze point. Houghton will responsibly manage the glycol disposal process. Website: http://www.houghton.com More Info: Houghton Chemical Specialized Glycol Services.pdf
