An exceptional three vessel HERMS system built entirely using Tri-Clamp components. Designed and built without compromise, the HERMS Trio Deluxe is the pinnacle of our brewing systems!

This 3 kettle, single tier HERMS system is comprised of 57L Craft hardware kettles: the 4/2 HLT, a 3/1 MLT, and a 4/1 Boil kettle. The three kettles and two pumps are connecting using a clever CIP ready stainless steel manifold with 9 quick clean ball valves that allows the entire brew process to be conducted without any hose changes. The system footprint is 136cm. Two equipment clamps are included, which allow mounting the entire manifold to the bottom of your brew table, keeping everything neatly out of the way. Please note, the maximum brew stand worktop thickness is 4cm.

For more information on product usage please see our HERMS Trio Deluxe brewing guide.

The heating elements in this set include a 3m connection cable with SCHUKO male plug, but do not come pre-wired to the elements. Please consult a professional electrician. You must be sure to use an appropriate GFI outlet and circuit breaker sized for the load.

Add the optional EINBREW 3V2P system controller for an easy to use and fully featured CE certified brew controller made by EINBREW in the UK. The optional EINBREW controller comes with a 3 PT100 temperature probes and all the power cables you need; just wire the heating elements to the supplied C20 plug ends and your system is ready for brewing!

Note: the stainless steel brew stand is for demonstration purposes only and is not included in the scope of delivery!

System Design

The hot water kettle contains one of the two 3.2 kW heating elements, the HERMS spiral adapters, a whirlpool fitting, a pickup tube, and a thermowell. At the output of the HERMS coil, the small tee fitting is installed, into which a thermowell for the MLT temperature sensor is installed. In the mash tun is the Craft Hardware false bottom on the low 2cm stand, a dip tube, and the two-piece sparge arm. In the boil kettle comes the second heating element, a pickup tube, a whirlpool tube, and a thermowell. Mash and boil kettle outputs are connected together with a 1″ Tee fitting and pass through a 1″ sight glass before the pump inputs. Because the pumps are the low point in the system, the pump inputs have a tee fitting which provides a drain point. Each 1″ ball valve has its own drain to allow drying of the valve internals between brew sessions!

The kettle layout is reversible so that the HLT can be placed either to the left or right of the MLT, as desired.

During system preheating, the temperature sensor in the HLT is used to control system temperature. After dough-in, control of the system temperature is switched to the temperature sensor in the HERMS coil output in order to accurately maintain the desired mash temp setpoint. The wort from the MLT is recirculated through the HERMS spiral heat exchanger to gently and safely maintain and raise the mash temperature. Once mashing is completed, the wort is slowly pumped from the MLT into the brew kettle, while simultaneously pumping the sparge water from the HLT into the MLT. During this process, the HERMS coil is cleaned on the inside by the hot water from the HLT. While boiling, the temperature sensor in the boil kettle is used to detect boiling and for cooling temperature measurement. Note, suitable cooling equipment is not included.

Because of the many components and connections, you probably won’t want to disassemble your entire brewery after every batch. However, you can remove each kettle individually for cleaning by disconnecting only two tri-clamps. Furthermore, the system is designed to be CIP friendly to every extent possible: The manifold uses all 1″ size components (dip tubes, valves, tees, sight glass, elbows, gaskets). Care is taken to provide the right size ID gaskets for each connection to ensure they are CIP optimized. The 1″ Ball valves are equipped with a drainage port to allow complete drying of the internal area between the valve body and the ball seat. After initial system cleaning, simply recirculate your heated cleaning solution through the system from start to finish. Finish with a rinse and open the ball valves drain ports – finished!

Comparison to the HERMS Duo System

The main advantages of the HERMS Trio compared to the HERMS Duo are:

  • No hose changes or system reconfiguration required during the entire brewing process
  • Larger batch capacity
  • Better system efficiency through full sparge method compared to the semi-sparge method
  • Additional features such as a sight glass, drainage ports, and fermenter output valve are included with the set

Batch Size

Small batch size: you can brew as small as 15L batches of 13P wort. Keep in mind that at 3 L/KG mash thickness the mash tun will only be about 12L full. Also you will need additional sparge water in the hot water tank to cover the HERMS coil completely. The extra water can be used for cleaning.

Large batch size: you can brew up to 45L batches of 13P wort. At this original gravity the only limitation is the volume of the boil kettle. For stronger beers, you can brew 45L up to 21P wort by mashing a bit thicker at 2.5 L/KG. In this case the limitation is the size of the mash tun.
