On the 1.5-7BBL systems, the PTC Power Box comes ready for install and should be hard wired to the power main. The heating elements, pump and level controller are all powered through the Power Box. A standard 15A (120V in Canada/US) circuit should be near the brewing area to power the ETC temperature sensor, as well as one near the fermenting area to power each ETC and Water, Beer and Wort Chillers (if used to maintain fermentation temperature). And if you purchase additional PBC (240V/22A) Power Box controllers for single element warming the fermenter during fermentation at 2% output, they come with a NEMA 14-30 receptacle.

 

See 'Humidity Venting Requirements' section below regarding electrical  requirements for cooling.

 

Water Requirements

Most customers find a 3/4" water line is sufficient. A water pressure regulator should be installed in the fermenter jacket supply line at or below the jacket pressure limit (5psi for 3-in-1 fermenters and 7psi for 4-in-1 fermenters). For quickest chilling, flow rate for chilling when using tap water should be not less than 3%/minute of total wort volume (ie. min. 20L or 5gal/min on the larger systems). A closed-loop plate chiller (out from and back into the fermenter) can also be employed in addition to the jacket to reduce the duration of post-boil chill. Total water volume per batch is as low as about 2 times beer volume (1x for beer, about 0.5x for mash/grain/boil losses and about 0.5x for cleaning) and typical cooling water for getting rid of boil heat is 2-3x beer volume depending on chilling water temperature.

 

Humidity Venting Requirements

Each municipality and space will have unique venting requirements based on occupancy so confer with local code. Venting directly outside is normally the easiest way to control humidity if permitted; the lid of the fermenter can be lowered with the hoist to within about 1" of the fermenter during the boil, and the steam elbow/vent attached to the center port on the lid with a flexible hose/duct connected to the vent and a fan drawing air through the hose/duct and pushing it outside. If venting outside is not an option, internal dehumidifiers can be used. As an example, 3 Dogs Brewery (White Rock, BC) is in a 1600sf commercial space (open concept) with 50 seat tasting room, and uses two 3t ac units (the general rule is 1t/250sf). They run three 75pint/day dehumidifier units plumbed to their condensate drain and vent vapor from the boil (using a 5" hose and fan) into these units; they keep humidity at about 45% and within a few hours of boil, the units have returned humidity to those levels. Gas (CO2) and heat (other than vapor) are relatively small and generally managed by venting requirements for the occupancy load (peak occupancy will in most tasting room situations produce more CO2 and heat than fermentation). If there is no, or low occupancy and high production volumes, these numbers should be factored in. (3 Dogs also has a 3t cooling unit for their walk-in cooler where they store their kegs, with dehumidification plumbed to the condensate drain.)
