OPTIONS

The following optional features may be included in your water heater. Reference the drawing specific to your heater for further details.

Single Solenoid Safety System

A single solenoid safety system closes the steam supply to the control valve should the temperature in the tank reach the high limit set point. This option requires 120-volt, 5-amp electrical service.

Double Solenoid Safety System

A double solenoid safety system dumps over heated water in the storage tank to drain in addition to closing the steam supply to the control valve. This option requires 120-volt, 5-amp electrical service.

Anticipator Control System

The anticipator control system forces incoming cold water over the control valve sensing bulb in order to begin heating water immediately.

Skid Mounting

Optionally, the unit may be mounted on heavy duty all welded I-beams.

Circulating Pump Package

An intra-tank circulation pump package with On/Off switch to continuously circulate water within the tank and thereby reduce stratification may be installed. An all bronze circulator pump.

Dial Temperature and Pressure Gauge

A combination temperature (70° - 250° F) and pressure (0 – 200 psi) gauge with 2½-inch dial may be factory installed in the tank.

STH, ST specifications

Hubbell ST and STH connectors are pivotal components in the realm of power and data transmission. Known for their durability and reliability, these connectors are widely implemented in both commercial and industrial applications. Their design caters to the need for efficient connectivity while ensuring safety and performance.

The Hubbell ST connector is engineered with a robust, user-friendly configuration that allows for quick and simple installations. It features a bayonet-style coupling mechanism, which ensures that the connection is secure and resistant to accidental disconnection. This design is especially beneficial in high-vibration environments, making it ideal for use in various industries, including telecommunications, aerospace, and manufacturing.

On the other hand, the STH connector is specifically designed for high-temperature applications and environments where harsh conditions prevail. It is made from high-temperature materials that can withstand significant thermal stress, thus ensuring consistent performance even in challenging conditions. This feature is particularly crucial for industries such as oil and gas, renewable energy, and any sector that relies on high-performance machinery.

Both ST and STH connectors utilize advanced technologies to enhance their performance. They incorporate precision-engineered contact surfaces that allow for optimal electrical flow, while minimizing signal loss. This is especially important in data-intensive industries where maintaining signal integrity is critical. Additionally, these connectors feature insulation systems that provide protection against moisture, dust, and other environmental factors, significantly prolonging their lifespan.

One of the standout characteristics of Hubbell connectors is their versatility. They come in various configurations and sizes, allowing them to cater to a wide range of applications, from telecommunications to industrial machinery. The connectors can handle different voltage levels and current ratings, thus accommodating the requirements of diverse operational setups.

In conclusion, Hubbell ST and STH connectors represent reliability and functionality in connectivity solutions. Their robust construction, advanced technologies, and adaptability make them a top choice for professionals looking for efficient and dependable connectors in demanding environments. Whether it’s ensuring seamless data transmission or providing power to critical systems, Hubbell connectors stand out as a preferred solution across many industries.
