Industrial Unit Heater

Product Overview

Here at Shunda, we've spent nearly twenty years refining HVAC solutions for industrial settings, and our Industrial Unit Heater is a prime example of this focus. Essentially, it's a heavy-duty heater that uses circulating hot water to warm up large, open spaces efficiently.

What makes it particularly useful for places like factories and warehouses is its overhead design. By installing this Hot Water Unit Heater from the ceiling, you keep all your floor space free for equipment and workflow. The unit pulls in air, moves it across a heat exchanger warmed by hot water, and then pushes out a consistent, comfortable warmth. We find this method does a much better job than standard systems at eliminating those annoying hot and cold spots, especially under high ceilings.

So, if you need reliable temperature control without sacrificing floor area, this Suspended Unit Heater, built with Shunda's proven durability, is designed for exactly that.

Where It Works Best

Over the years, our customers have put our hot water unit heater to work in all sorts of demanding settings. If you're managing a manufacturing floor, a large production area, or a drafty warehouse, you know how important—and challenging—consistent temperatures can be. That's where this suspended unit heater shines. By mounting overhead, it tucks neatly out of the way, heating the people and workspaces below without wasting energy on the empty air up high.

It’s not just for factories, though. We’ve seen great results in large commercial spaces like retail stores, sports complexes, and even agricultural buildings, where its even heat distribution helps maintain comfort without spiking the energy bill. The industrial unit heater is also a reliable choice for more specialized environments, from busy repair garages that need durable performance to food processing areas where temperature control is part of the process.

Wherever you need dependable, efficient heat without sacrificing floor space, this system is built to deliver.

What Makes It a Smart Choice

When we designed this industrial unit heater, we focused on solving the three biggest pain points our customers face: high energy costs, limited space, and the need for flexible solutions.

Let's talk numbers first. The efficiency speaks for itself - it delivers 23KW of real heating power while consuming only 0.26KW of electricity. That's not just a spec sheet claim; that's substantial savings on your monthly energy bills. The secret lies in the four-row pipe heat exchanger, which creates more surface area for heat transfer between the hot water and air. Compared to traditional electric or fuel-based heating systems, you'll notice the difference in your operating costs from day one.

Space is precious in any facility, which is why we designed this as a suspended unit heater. By mounting it overhead, you reclaim all your floor space for what really matters - your equipment and workflow. The compact 670mm × 670mm × 350mm footprint means it fits even in tight spaces where every centimeter counts.

But here's what truly sets us apart: we understand that no two facilities are identical. That's why every hot water unit heater we make can be customized to your specific needs. Unusual ceiling height? Special connection requirements? Unique thermal demands? We've probably already engineered a solution for similar challenges. Our team works directly with you to ensure the unit fits your space and operational requirements perfectly - because sometimes, off-the-shelf solutions just don't cut it.

This combination of proven efficiency, smart space utilization, and true customization is what makes our clients choose Shunda year after year.

Our Commitment to Quality & Key Technical Features

When you choose our hot water unit heater, you're not just getting a product – you're getting nearly twenty years of manufacturing expertise. Our 70,000 square meter production facility operates with a simple philosophy: build it right the first time. This commitment shows in every unit that leaves our factory, where comprehensive quality checks and modern production techniques ensure you receive a heater that will perform year after year.

The certifications on our wall aren't just for show – they're our promise to you. We've achieved ISO 9001 for quality management, ISO 14001 for environmental responsibility, and ISO 45001 for workplace safety. The CE Marking means this industrial unit heater meets strict European standards, while our National High-Tech Enterprise status reflects our ongoing innovation. Being actively involved with industry bodies like China's Refrigeration Industry Association keeps us connected to the latest standards and best practices.

Now, let's talk about what makes this suspended unit heater work so well in practice. The four-row pipe configuration represents the sweet spot between thermal performance and airflow efficiency – it's why we can maintain that 4000m³/h airflow while ensuring effective heat transfer. The 60℃ supply/return water temperature isn't arbitrary; it's the result of extensive testing to balance energy efficiency with reliable performance.

We build these heaters to withstand tough industrial environments. The housing uses durable, corrosion-resistant materials, and the entire unit – including the fan assembly and protective grills – fits within that compact 670×670×350mm frame. This thoughtful construction means you get a product that looks professional and stands up to demanding conditions.

Installation is straightforward too. The standard DN32 connections make piping work simple, while the suspension system is designed for secure overhead mounting with minimal structural impact. If your specific situation requires adjustments, our customization options ensure we can adapt the unit to fit your unique piping configuration or space constraints.
