# Thermal Fluid Heating Systems - Enerquip

## Overview
Enerquip specializes in the design of high-quality thermal fluid heating systems for industrial applications. These systems, also known as hot oil heaters, are used to heat fluids in a closed loop system for various industrial processes.

## How Thermal Fluid Heaters Work
- Use a heat transfer fluid (typically mineral oil or synthetic oil) that is heated by a gas-fired burner
- The heated fluid circulates through a closed loop system
- Heat is transferred from the fluid to the target material or process

## Key Features of Enerquip's Thermal Fluid Heating Systems
- High-efficiency serpentine coil radiant section
- High-efficiency gas-fired burner with burner management system (BMS)
- Finned convection (economizer) section - adds 10% efficiency
- 1,000-gallon expansion tank, with optional nitrogen blanketing system
- Recirculation pump
- NEMA 4 control panel with integrated safety features and alarms
- Pre-piped and pre-wired fuel train for natural gas and/or alternate fuels
- Sizes ranging from 1.3 MM BTU/Hr. to 40 MM BTU/Hr.

## Serpentine Coil Technology Advantages
Compared to traditional helical coil heaters, serpentine coil heaters offer:
- Even heat distribution
- Less oil degradation
- Longer tube life
- Higher operating oil temperature
- Easy maintenance
- Higher fuel efficiency (up to 90% L.H.V. with standard finned tube economizer)

## Low NOx Options
- Less than 30 PPM with upgraded burner and flue gas recirculation
- Less than 9 PPM with ultra-low NOx mesh head burner

## Industrial Applications
- Rubbers, plastics, and paper processing heat
- Chemical process heating
- Synthetic fiber production
- Surface coatings curing
- Various other industrial heating applications

## Benefits
- High fuel efficiency (can pay for itself in just over a year when replacing older units)
- Long service life (some units operating for nearly 30 years)
- Reliable operation
- Reduced maintenance costs
- Higher operating temperatures
