All valves are full-port 1/2″ NPT, with SS304 body construction and teflon seals, and are IP67 rated (wash-down capable). All valves have a position indicator an manual adjustment knob. Valves are 24VDC power (12 VDC are available on request). Three versions are available:

Proportional Valve – 2-way valve which will open to a percentage  proportional to an analog input voltage across the range 0 – 5 VDC. The valve has an LCD readout for opened angle and setup. The ball valve is slotted to create linearized flow across the range. The valve is wired via 4 signals: Power (24 VDC), Ground, Control Signal (0-5 VDC), and feedback signal (optional, 4-20 mA). Valve can be driven directly from the BruControl Analog Amplifer. Download the specification sheet/manual: BruControl KLD20T Proportional Valve.

2-way Valve – 2-way valve which will open or close fully depending the input signal. The valve is wired via 3 signals: Open (24 VDC), Close (24 VDC), Ground. The valve is appropriately directed via an SPDT relay or using two outputs on the BruControl UniShield and digital output “Dual-Throw” mode. Download the specification sheet/manual: BruControl KLD20S 2-Way Valve.

3-way Valve – 3-way valve which will assume left or right positions fully, depending the input signal. The flow path is in ‘L’ port configuration. This means it will connect the central port to either the left or right port, but not both or neither. The valve is wired via 3 wires: Open (24 VDC), Close (24 VDC), Ground. The valve is appropriately directed via an SPDT relay or using two outputs on the BruControl UniShield and digital output “Dual-Throw” mode.

The sensors measure liquid column above the sensor. The 50 millibar version (PSF-20-5) can measure approximately 18 in. / 455 mm above the sensor. The 100 millibar version (PSF-20-10) can measure approximately 36 in. / 910 mm above the sensor.  The volume which is measured is dependent on the vessel diameter. To calculate the volume and calibrate the sensor, use the Sensor Calibration Tool.

The heaters are welded in a 1.5″ tri-clamp cap so the element will mount in the 1.5″ tri-clamp RIMs tube of your choice (16″ – 18″ long recommended). The heaters are 15/32″ diameter (12 mm) and are 15″ long (380 mm) from the inside of the cap. Each heater has an individual supply (power + ground) to provide for wiring flexibility. The tri-clamp cap includes a stainless cover, and the wire bundle is covered by a PVC jacket. The wires are 10 feet (3 m) long.

All four wire bundles can be connected to their power sources at the end of their run, or alternatively, a 10 AWG, 3-wire cable can be run to the cover and the wires all terminated inside it.

All four heaters can be powered together (recommended), or individual elements powered to accommodate a specific application. For example, one element can be used for mashing while the others are separately turned on for strike water heating, mashout, and direct heat fly-sparging.

The QuadZilla comes with 3 baffles which may be installed by the user to create more turbulence in a RIMS tube, which will aid in heating during low flow periods, such as direct heat fly-sparging. The element can be easily removed for cleaning, though this should be needed infrequently due to the low heat density of the heaters. The entire assembly is made of 304 SS. Note: This element can theoretically heat water from freezing to 170 degrees F (76 C) sparge temperature at 1 quart per minute (1 lpm) rate. Room temperature 68 degrees Fahrenheit can be heated to sparge temperature at approximately 1.4 quarts per minute.

Please note the assembly does not include tri-clamp gaskets, clamps, or any other accessories other than the baffles. No element “enclosure” is required. It is strongly recommended that the RIMs tube be oriented vertically for proper performance during mashing and direct heat fly-sparge heating.
