Hammer Arrestor

A hammer arrestor is a plumbing device designed to absorb spikes in water pressure. It consists of a chamber filled with air that will compress when a surge of water is introduced into the water line. An indication of water hammer is clanging or noisy pipes and perhaps fluctuations in water pressure.


Heaters

The tank heater is a device used to heat the water in the tank. It is quite similar to the heating elements found in common household appliances, such as water heaters, ovens, and clothes dryers to name a few. Its construction is a high heat-resistive element encased in a heat-treated stainless steel tube. Magnesium oxide powder is used as filler and insulation to keep the resistive wire in place and away from the casing. Elements are built for specific applications and are not necessarily interchangeable. They are rated for applied voltage and a specific power output (wattage), which will determine the resistance (ohms value).


High Intensity®

Technology that mixes high viscosity concentrates thoroughly, consistently, and accurately to the required brix setting. The consistent results ensure the best quality beverage in the cup and contribute to maximum profits in the beverage program.


Hydolysis (relating to coffee)

A chemical reaction where the materials created during extraction break down further into water-soluble proteins and sugars. Part of the brewing process that includes wetting and extraction.
