The Accustat® Independence line of thermostats by PSG Controls provides a mercury-free option for facilities needing a tamper resistant control with fixed temperature set points. The Independence uses preset electronic fixed temperature set points to maintain desired comfort settings. These thermostats can be used in a variety of commercial applications such as warehouses and fast food restaurants, or residential applications such as condominiums or other managed properties.

Accustat Independence thermostats from PSG Controls are available in eight models.

The Accustat Independence line contains no mercury, and therefore provides a solution to facilities located in states that have passed legislation banning the sale of mercury, which extends to mercury sensor products. These states include Connecticut (since 2004) and California (since 2006).

Bi-metal or mercury based mechanical thermostats are virtually maintenance-free, but struggle to maintain precise temperature accuracy. This often results in occupant discomfort which encourages them to change temperature settings resulting in large temperature swings and high energy bills. Electronic and/or digital controls control temperatures precisely, but do require an extra wire for power, and/or batteries. The design of the new mercury-free Accustat Independence thermostats addresses these issues by providing precise temperature and locking tamper-proof cover, as well as not requiring batteries or extra wires.

For facilities already using Accustat thermostats, the eight models in the Independence line are available to cross over from existing models.

Innovex Technologies, a provider of components for heating and cooling systems, recently introduced its new iWorX^TM valve series for heating and cooling—two position, modulating and floating actuation valves featuring accurate control and durable construction.

The new ZV series, MV series and FV series valves are designed to increase comfort and reduce energy consumption while providing durability and performance at a competitive price. The valves can be used in a variety of applications where accurate control is required. These include hydronic systems, residential zone systems, fan coil units, and reheat on commercial terminal box units just to name a few.

By accurately controlling flow, these valves reduce sudden changes in supply temperature and provide heating and cooling more evenly. The Innovex line offers two position actuation in the ZV series, as well as complete modulated solutions in the MV series (modulating actuator) and FV series (floating actuator).

All ZV, MV and FV series valves determine the correct action required by responding to a thermostat or building automation system output signal. This provides accurate control of chilled or hot water into the controlled medium, cooling or warming the conditioned space as required. When the desired temperature is reached, the valve returns to its original position and powers off, which helps reduce energy consumption.

The base and cover of all ZV, MV and FV series actuators are constructed of specially engineered flameproof polycarbonate. All valve bodies feature durable EPDM rubber and stainless steel internal construction providing exceptional performance even in the harshest environments.

The entire line of ZV, MV and FV series valves are available in two way and three way configurations and in 1/2″, 3/4″, 1″, and 1 1/4″ sizes with a variety of connection types, including inverted flair. This allows these valves to be used in a range of new construction and retrofit applications.
