Cold storage and industrial refrigeration facilities are designed to do one thing exceptionally well: keep things cold. But behind every reliably frozen warehouse or temperature-controlled processing space is a carefully balanced system—and low-pressure boilers play a much bigger role than many people realize.
Natural gas–fired and fuel-fired low-pressure boilers quietly support refrigeration operations every day. When they’re running properly, the cold side performs better. When they’re not, inefficiencies, downtime, and operational headaches start to pile up quickly.

Why Cold Facilities Need Boilers at All
It may seem counterintuitive, but heat is essential in cold environments. Low-pressure boilers provide controlled steam and hot water that help refrigeration systems operate efficiently and safely.
Defrost Systems That Keep Refrigeration Moving
One of the most critical boiler-driven applications in cold storage is defrost.
Low-pressure steam is commonly used for:
-
Evaporator defrost
-
Preventing ice buildup on coils
-
Maintaining airflow and heat transfer efficiency
Without effective defrost, ice accumulation reduces capacity, increases energy consumption, and puts unnecessary strain on compressors. Reliable steam ensures defrost cycles are predictable and effective—keeping refrigeration systems doing what they’re designed to do.
Freeze Protection & Building Integrity
Cold storage facilities operate in environments where freezing isn’t just expected—it’s intentional. That creates risk for piping, utilities, and building infrastructure.
Low-pressure boilers help:
-
Protect piping and valves from freezing
-
Maintain warm zones around docks, vestibules, and mechanical rooms
-
Support slab heating systems to prevent frost heave
These functions may not generate revenue directly, but when they fail, the consequences are immediate and expensive.
Supporting Food Safety & Sanitation
Many cold storage facilities support food processing, distribution, or ready-to-eat operations. Steam and hot water from low-pressure boilers are used for:
-
Washdown and sanitation
-
Cleaning equipment and floors
-
Supporting hygiene programs tied to regulatory compliance
Even in cold environments, sanitation standards remain high and boilers help meet them.
Facility Heating & Personnel Comfort
Cold facilities don’t stop at the freezer doors. Offices, maintenance areas, and employee spaces all require heating and hot water.
Low-pressure boilers supply:
-
Space heating
-
Domestic hot water
-
Comfort systems that help keep teams productive and safe
Because even the coldest operations still rely on people.
Natural Gas–Fired vs. Fuel-Fired Boilers in Refrigeration Facilities
Cold storage operators often select boiler types based on site infrastructure and reliability requirements.
-
Natural gas–fired boilers offer clean operation, fast response, and efficiency.
-
Fuel-fired or dual-fuel boilers provide redundancy and flexibility, especially in regions with supply constraints or extreme weather concerns.
In either case, uptime matters—because refrigeration systems don’t get days off.
Why Cold Storage Facilities Choose Genemco
At Genemco, we understand the reality of refrigeration operations: when one system goes down, others feel it immediately. Boilers may not be the largest piece of equipment in a cold storage facility, but they are often among the most time-sensitive.
Facilities turn to Genemco because we offer:
-
Pre-owned and refurbished low-pressure boilers ready for industrial environments
-
Quicker access to equipment when timelines are tight
-
Cost-effective solutions that help manage capital budgets
-
Industry knowledge rooted in industrial refrigeration and food facilities
We know that in cold storage, delays can turn into product loss quickly. Our focus is helping you avoid that scenario.
A Practical Backstop for OEM Projects
If you’re an OEM selling a new boiler into a cold storage or refrigeration facility, extended lead times can put everyone in a tough spot. The customer still needs to maintain defrost, freeze protection, and sanitation—regardless of project timelines.
That’s where Genemco can quietly step in:
-
Providing a temporary solution that keeps systems stable
-
Helping your customer avoid emergency shutdowns
-
Giving your project the time it needs to be done right
We’re not here to compete with your long-term solution. We’re here to help you protect the relationship by ensuring your customer stays operational until the new equipment arrives. When things stay running smoothly, your solution arrives under far better circumstances—and your customer remembers who guided them through it.

Keeping Cold Operations Balanced
Cold storage and industrial refrigeration facilities are a constant balancing act between temperature, efficiency, safety, and uptime. Low-pressure boilers may operate in the background, but their impact is felt across the entire system.
At Genemco, we support that balance, helping operators, engineers, and OEMs navigate challenges with practical, dependable equipment solutions.
