In hazardous locations and high-risk industries, the Hubbell Explosion Resistant (ER) Water Heater is ready
for any challenge. Resistance ER is engineered for operations in locations like oil refineries,
drilling platforms, paper and pulp mills, and industrial facilities. Let's explore how this water heater shines
in the industries it serves.

Sealed Heating Element for Resilience
The highlight of this product is the explosion-resistant sealed heating element. Consider the petrochemical industry, where explosive vapors may occur. For such a high-risk environment, this airtight feature ensures the safe and uninterrupted supply of hot water. The sealed heating element is unique to Resistance ER.

UL and CSA Ratings for Safe Operation
Hubbell Explosion Resistant Water Heater is UL and CSA listed with a housing rated for operation in Class I, Division 1 & 2, Groups B, C, & D, along with Class II, Division 1 & 2, Groups E, F, & G. These ratings make it ideal for refineries, where flammable gases are ever-present, and drilling platforms, which operate in remote and challenging offshore locations. In these hazardous locations, Resistance ER ensures a dependable hot water supply without compromising safety.

HydraStone™ Cement Lining for Extended Tank Life
Resistance ER is a HydraStone cement-lined water heater, one of the longest lasting and most durable water heaters available. This is paired with copper-silicon alloy tappings and a high-impact composite jacket that won't rust or corrode. In paper and pulp mills, where combustible dust may occur, this heater's resilient build guarantees safe and reliable operation.

Factory-Selected Controls and Easy Installation
From chemical plants to manufacturing facilities, Resistance ER’s factory-selected controls offer a hassle-free installation process, reducing downtime. Resistance ER is also ready for electrical and plumbing service connections, simplifying setup. With that, installing ER may enhance your operational efficiency. 

In hazardous locations, Hubbell Resistance ER is a safe choice. Its robust features like the cement lining and sealed heating element make ER a reliable asset. While UL and CSA ratings for safe operation underscore Resistance ER’s credibility. With applications spanning from oil refineries to drilling platforms, paper and pulp mills, and industrial facilities, ER is setting a new standard for safety.
