Emergency Industrial Equipment Sourcing: A 7-Step Checklist for Howden Compressors, Fans, and Heat Exchangers

Who this checklist is for

If you're here because a compressor failed and the line is down, this checklist is for you. I'm a service engineer at Howden. In eight years, I've handled more than 200 rush orders, including same-day turnarounds for refinery, food processing, and chemical plant clients. I'm writing this from what I know as of early 2025. Pricing and lead times move fast, so verify current details when you call.

Quick note: if you arrived looking for Howden Group commercial insurance services, that's a different business. This article is about Howden the industrial engineering company — compressors, fans, blowers, refrigeration equipment, and heat exchangers.

There are seven steps below. Follow them in order. If you only get one thing from this, make it step one.

Step 1: Verify the failure before ordering anything

The first thing I ask isn't 'what do you want to buy?' It's 'what exactly is broken?'

In March 2024, a client called at 2 p.m. saying their process line was down. They wanted a new compressor. Normal turnaround for a replacement unit is 10 days. We sent a technician by 6 p.m. It turned out to be a blocked discharge valve. The line was running by 9 p.m. No compressor needed.

Checkpoint: talk to the person who was there when it failed. Get the actual fault code, the vibration reading, or the pressure drop. Ordering a compressor because the screen says 'fault' can turn a $500 repair into a $50,000 mistake.

Step 2: Get the operating envelope, not just a part number

For a replacement unit—especially something like a Howden Thomassen compressor—the nameplate data is not enough. You need the full duty conditions. For compressors, that means inlet pressure, discharge pressure, gas composition, ambient temperature, and allowed trip settings. For fans and blowers, it means flow, static pressure, gas density, and shaft power.

This matters more than the part number. A compressor that's 10% under capacity will trip on load. A fan that's oversize can cause motor overload or system instability. I've seen both.

Checkpoint: write down at least six numbers before calling your supplier. If you don't know the gas composition, don't guess—ask the process engineer.

Step 3: Know the difference between heat pump and HVAC applications

This is the step most people skip.

If you're replacing a component in a heat pump dryer, standard HVAC equipment is not automatically a like-for-like replacement. Heat pump vs HVAC is not just a label. A heat pump dryer uses a refrigeration circuit to transfer heat, and the air side has to work against the pressure drop of the drying chamber and the material load. An HVAC fan is often designed for free discharge or duct systems with different static pressure. So the fan and compressor need to be matched to the actual dryer duty.

To give you an idea: a residential Vornado fan moves air at just a few inches of water gauge. An industrial dryer may need 6 to 12 inches or more. There is no comparison.

Checkpoint: if your system says 'heat pump dryer' on the nameplate, use components rated for the refrigerant and operating envelope. Do not assume HVAC rated parts will survive.

Step 4: Ask about stock and lead times before asking about price

At Howden, we keep certain compressor packages and replacement parts in stock, but not everything. The quickest way to find out is to ask directly: 'What's the current lead time for this exact model?'

For Howden Thomassen compressors, ask about aftermarket options too. In my experience, a supplier can often find a replacement, a return, or a refurbished unit if they already know the duty conditions.

Last quarter alone, we processed 47 rush orders with 95% on-time delivery. Maybe 46, I'd have to check the system—but it's that range. That did not happen by accident. It happened because we checked availability, freight options, and shop capacity before promising anything.

Checkpoint: get the lead time in writing. 'Probably a few weeks' is not a lead time.

Step 5: Calculate the cost of downtime before you decide on shipping

I used to think rush fees were just vendors taking advantage. Then I saw the operational reality.

Why does the rush fee matter? Because if your plant loses $10,000 per hour when a line is stopped, paying $800 for overnight air freight is not a waste. It's the cheapest hour of the day.

In 2023, a food processing customer waited two days to save $800 on standard freight. The line was down for those two days. The lost production was far more than $800. We learned that mistake together. Now we ask every client the same question: 'What is your downtime cost per hour?'

Checkpoint: if you don't know the hourly cost of downtime, treat the rush fee as an insurance premium. It's usually worth it.

Step 6: Ask the supplier for a smarter alternative

Small orders get ignored a lot. I understand why some companies focus on big contracts. But at Howden, we treat a $200 order the same as a $20,000 order, because that's how long-term relationships start. When I was a junior engineer, the vendors who treated my small orders seriously are the ones I still use for large projects.

Don't be afraid to tell the supplier what you need and ask if there's a different model that fits the same duty. Sometimes a reverse-flow fan or a different compressor frame size can solve the problem faster than the exact part.

In one case, a client needed a specific large fan for a dryer. We did not have that exact model in stock, but we had a different fan with the same duty point. We shipped it the same day. It was not a downgrade—it was a better physical fit for their foundation.

Checkpoint: after you get the lead time, always ask one more question: 'Is there anything in stock that can meet this duty?'

Step 7: Make sure the after-sale plan is written down

Getting the equipment to the site is not the finish line. Installation, commissioning, and warranty support are part of the emergency too.

In April 2024, a customer received a new screw compressor 36 hours after ordering it. It sat for three days because the lifting lugs did not line up with their old foundation. Nobody had checked the mounting dimensions. That was an easy fix, but it turned a 36-hour supply chain win into a four-day total wait.

For a project with a $50,000 penalty clause, we paid $800 in rush fees and saved the project. That part was worth it. But the installation question is what saved us on another project—we verified the motor rotation direction before shipment and caught a wrong phase.

Checkpoint: before you accept delivery, confirm the delivery address includes access for a crane or fork truck, the mounting dimensions match, and the person who will connect the power has read the wiring diagram.

Common mistakes I keep seeing

Don't call from memory. Part numbers get written down wrong. I do not mean 'maybe wrong.' I mean consistently wrong across many orders.

Don't assume a standard motor fits. A Vornado fan motor has nothing in common with a 50 kW industrial fan motor. The shaft diameter, enclosure, and voltage all matter.

Don't skip the performance test certificate. If the supplier won't provide a test certificate, that's a red flag.

And please don't ask for a quote without telling the supplier it's an emergency. I can move faster when I know the deadline is real. We all can.

Final thought

If you're here because you typed 'Howden Group commercial insurance services,' this article was written for a different Howden. But if you're an engineer with a dead fan, a failing compressor, or a heat exchanger issue, this checklist is the shortest path to a working line. Small order or large order, the process is the same. Small doesn't mean unimportant—it means potential.
