A laboratory fume hood system for cooling at least one laboratory device located in an interior work area comprises a heat exchanger system having a heat exchanger in thermal communication with a primary fluid loop containing chilled fluid and a secondary fluid loop containing a cooling fluid which is in thermal communication the laboratory device. The primary fluid loop is located behind the fume hood wall and not in the interior work area.

An apparatus for providing coolant fluid to a device, the apparatus includes a heat exchanger having a hot side and a cold side. The cold side is in fluid communication with a chilled fluid supply and adapted to receive a first fluid from the chilled fluid supply in a first inlet and return the first fluid from the cold side to the chilled fluid supply. The cold side and the chilled fluid supply form a first fluid circuit. The apparatus further includes a second fluid circuit in fluid communication with the hot side, means for introducing a second fluid within the second fluid circuit and integral thereto, a pump integral to the second fluid circuit and adapted to transmit a second fluid within the second fluid circuit and means for controlling a rate of flow of the second fluid within the second fluid circuit. The device is within the second fluid circuit and the means for controlling the rate of flow operates in the absence of internal recirculation.
