STEPHEN TURNER INC COMMISSIONS MIT'S FIRST AMMONIA CHILLER

The MIT W34 Johnson Ice Rink Chiller Replacement Project consisted of the demolition of the existing DX refrigerant brine chiller and the installation of an anhydrous ammonia refrigerant (R-717) brine chiller, ventilation system, and an ammonia detection system. Stephen Turner Inc. commissioned the new chiller, ventilation system, and ammonia detection system, wrote the Standard Operating Procedures (SOP), and documented the sequences of operation and setpoints for these systems. This ammonia chiller was the first of its kind at MIT.
