UB20 In-Line Heating System: Safe Portable Heating for Emergency Shelters

Maintaining safe, warm working conditions in emergency shelters and confined spaces can be challenging. Cold environments slow down operations, reduce comfort, and create additional safety risks for workers and occupants.

The UB20 In-Line Heating System solves this challenge with a reliable indirect-fired design that delivers clean, uncontaminated warm air. It runs on a standard 120V circuit and works with common propane tanks, making it easy to deploy in demanding conditions. 

In this article, we explore how the UB20 In-Line Heating System works and why it is the ideal choice for emergency and industrial settings.

Challenges Faced in Emergency Shelters

Emergency shelters are often set up in harsh and unpredictable conditions where maintaining safe temperatures becomes a major challenge. Cold environments can slow down operations and increase discomfort for workers who spend long hours in confined spaces.

Emergency responders struggle to find heating solutions that are both safe and practical for enclosed areas. Traditional heating solutions can release fumes or moisture, creating air quality concerns that put workers and equipment at risk.

Power availability adds another layer of difficulty. Some heaters require specialized electrical setups or heavy-duty power sources, which are not always accessible in remote or rapid-deployment locations.

Fuel compatibility is another concern in temporary shelters. Teams often need equipment that runs on standard, easy-to-source fuel options instead of specialized or hard-to-transport systems.

These challenges highlight the need for a portable, clean, and reliable heating system designed specifically for confined, emergency, and industrial environments.

Overview of the UB20 In-Line Heating System

The UB20 In-Line Heating System is designed to provide safe and reliable warmth in emergency shelters and confined industrial spaces. It is designed for quick deployment where controlled heating is essential.

This system uses an indirect-fired heating process that keeps combustion separate from the airflow. As a result, it supplies clean air without exposing workers to fumes, fuel odors, or exhaust contaminants.

It operates on a standard 120V circuit, which makes setup simple in most field environments. There is no need for specialized power sources or complex electrical installations.

The heater runs on propane and works with common tank sizes. A standard 20lb propane tank provides up to 10 hours of continuous heating, making it highly practical for demanding operations.

Key Specifications of the UB20 In-Line Heating System

The UB20 In-Line Heating System comes with a set of well-engineered features that support safe and efficient heating in demanding environments. Below are the key technical specifications that define its performance and reliability.

  • Indirect-fired heating design

The system uses an indirect-fired heating method that keeps combustion separated from the airflow. This ensures clean, uncontaminated warm air enters the shelter or confined space.

  • Stainless steel heat exchanger

A durable stainless steel heat exchanger transfers heat efficiently without exposing users to combustion byproducts. This design increases safety and extends the lifespan of the unit.

  • Standard 120V power compatibility

The heater runs on a regular 120V circuit, allowing quick setup in most locations without specialized wiring. This makes it ideal for emergency scenarios where power access may be limited.

  • Propane-fueled operation

It connects to common propane tanks used in industrial sites. With a standard 20lb propane cylinder, it can deliver up to 10 hours of continuous heating.

  • Portable heater (HA01) included

The package comes with the HA01 portable heater, designed for mobility and simple deployment. Its compact form makes it suitable for temporary or remote environments.

  • Quick-couple duct canister

A quick-couple canister with a flexible duct, available in 15ft or 25ft lengths. This allows warm air to be directed precisely where it is needed.

  • High-flow propane regulator

A high-flow regulator is provided to ensure consistent fuel delivery from the propane tank. This helps maintain stable heating performance throughout operation.

  • Compatibility with UB20 ventilators

The system integrates seamlessly with UB20 confined space ventilators such as models ED7002 and ED8002. This compatibility allows teams to build complete heating and ventilation setups.

  • Support for quick-couple duct systems

It works with RAMFAN’s quick-couple duct canisters and flexible ducts for extended airflow management. These accessories help improve reach and airflow control in complex environments.

  • Propane cylinder standard compliance

The system is designed to work with propane cylinders that conform to ANSI/NFPA 58-1986 standards. This ensures safe operation and easy access to fuel sources on most job sites.

Applications of the UB20 In-Line Heating System by Industry

The UB20 In-Line Heating System is versatile and designed to meet the heating needs of multiple industries. Its safe, portable, and efficient design makes it ideal for emergency, industrial, and confined space environments.

  • Emergency response and disaster relief

The UB20 In-Line Heating System is ideal for emergency shelters and disaster relief operations. It provides safe, warm air to displaced populations without exposing them to fuel fumes or exhaust, ensuring comfort and safety in temporary setups.

  • Industrial and construction sites

In construction, maintenance, or confined industrial areas, the UB20 delivers controlled heat for workers and equipment. Its portable design and standard propane compatibility make it easy to deploy in remote or temporary job sites.

  • Utilities and confined space operations

The system is well-suited for confined spaces such as utility tunnels, vaults, and underground maintenance areas. Indirect-fired heating ensures workers receive clean, uncontaminated air while working in tight, enclosed environments.

  • Temporary shelters and field facilities

Organizations that operate temporary field offices, workshops, or shelters can rely on the UB20 for consistent warmth. Its flexible ducting and compatibility with UB20 ventilators allow efficient distribution of heat throughout the space.

  • Industrial drying and equipment heating

The heater can also support industrial processes that require controlled warm airflow, such as equipment drying or pre-heating components. Its safe, indirect-fired design prevents contamination of sensitive materials or stored goods.
