"We want to acknowledge that AIHTI product & shipping quality has dramatically improved since we started selling your product many years ago. (2005)
The shipment under your order no. 0177811 was received in excellent condition. The Oil Cooler was crated, bolted and attached directly on a fixed pallet and then stretch wrapped.

Product quality from manufacturing, paint finish to labelling and boxing, crating etc. has all improved over the years. Whatever you are doing keep it up. Your staff gets it right!

Keep up the good work and pass these comments onto fellow workers from plant to packaging to shipping."


"I really appreciate your help on EVERY heat exchanger I’ve called you about. You make it very easy to for me and my associates to do business with AIHTI."


Subject: AOCS 3525 Cooler


I don’t have JR’s email, so could you please forward this to him?  So far, the cooler we purchased from you is working great!  Colorado is a challenging environment for an oil cooler because the temp can go from the 20’s to the 70’s in an 8-hour period.  The high altitude also adds in some challenges.  We have the unit wired onto a VFD that is controlled by a PLC-based temperature controller and the unit is easily maintaining oil temp to within 2 degrees of a setpoint.  August may be challenging when it get into the 90’s, but from what I see so far, it looks like it will handle it!  We are very pleased with how this project turned out!

Anyway, thanks again to all at AIHT to helped us with this.  Your customer service and knowledge has been outstanding! 


We received the cooler this morning and I wanted to thank the whole group down there for the great job.
The cooler looks excellent. The crating was good. The cooler was well protected.
Some attention really went a long way here.

You should all be proud of still giving the customer very acceptable service. Something most companies fail to provide.

I don’t know of many companies that operate at the efficiency of AIHT and Ive been doing this for 30 years.

"I just wanted to take a minute and thank you and American Industrial for a great job that was done on this HE project. We installed the units last weekend and I followed up with the customer this morning. He said the units are working great."

I am writing to thank you for your excellent service on completing our oil cooler (AOCS2010) so quickly. I know we will be working together well into the future.


I wanted to thank you and your staff for the excellent service with getting a oil cooler to me so quickly.  I placed the order on 7/9/13 and had it hear at our shop as you promised by 7/12/13.

As I explained to you that I have a excavator with a hydraulic hammer that is down due to a heat issue.  your  quick response with getting this out to me so fast will have us back up in running over the weekend.

Now thats what I call EXCELLENT customer service and support!

Thank you again,


Please pass this along to your staff members.

Just want to let you know that we appreciate the good service and lead-times given by your staff. We also like the way our shipments are coming in. Lots of wood, stretch wrap. Bullet proof.

Keep it up!
