HydroCowl enclosures are designed to freeze protect water systems in -30F climates with a heat source and withstand up to 130 mph wind gusts. All units have an insulated, hinged drain for water discharge. All units are designed for key-lock security from vandals. The removable panel locks are all keyed alike for multiple enclosure installations. The standard material is 18 guage mil-finish aluminum (also available in colors) with optional materials, stainless steel and galvanized steel.

Model Series 100 and 200:
 

Models 100S-AL and 200S-AL are one piece, "lift-off" design enclosures for 1" and 2" plumbing systems. A mounting bracket is anchored to the concrete pad which fits within the inside width of the enclosure. The enclosure is secured by insertion of a stainless steel pin through the enclosure and mounting bracket. The pin receives a pad lock on one end.

Model Series 300, 400 and 600:

Model series 300 through 1000 are panel design enclosures. The enclosures are fabricated as composite panels of insulation, metal skin, and structural members. All of the panels easily interconnect to form an extremely strong enclosure with no open seams.
