I’ve used units from other manufactures, and there is NO comparison to yours.   The quality is far more superior to the others, and the unit is designed to keep the operator safe. I purchased a Hotbox earlier this year, and the experience was just as great.  K&M you have a customer for life!!

The people at KM were not only interested in selling the equipment, they wanted to educate us on the infrared process. Infrared Repair is now a full service we offer, and we use KM International equipment because it is quality and they provide “personalized” service. They are never too busy for the customer.

The friendly staff at KM INTERNATIONAL showed me how to operate the KM 4000 and we immediately started to stock pile our extra asphalt and have used this machine numerous times with hot available asphalt all day long. Waste is no longer an issue.

I purchased a KM 4-48 and KM 4000 hot box in May … since then I am very happy with the units and have increased my gross income by 25%-30%. I am very happy with the equipment, personnel, and company (KM International), and HIGHLY recommend them to anyone looking to expand their asphalt maintenance business.

The KM hot box is the most used piece of equipment in our asphalt maintenance program and I am very happy to report we have had no issues with this unit after two years of more use than we anticipated. As a smaller community we only have one asphalt hot box, so reliability is of utmost importance to us.

We have using this machine (KM 55) for a month now and I couldn’t be happier with the results. My crew wanted to know why I didn’t get one years ago. No more babysitting the crack seal machine, no more noise from the large trailer units, and no more worry that the direct fire unit will blow up at some point and hurt somebody.

We purchased a Hot Box and an Infrared Recycler from KM International in April and it has taken our company to levels we never imagined.
The owners and staff at KM International are second to none in customer service and professionalism. We at Semper Fi Paving are absolutely honored to be a part of the KM International family and can’t wait to see what the future holds. We cannot thank KM International enough. SEMPER FI

I just wanted to take a minute and comment on Cliff and the “KMers”. I’ve been a repeating customer of Keizer Morris for 11 years now, buying equipment that ranges from 6000 gallon bulk tanks to hot boxes, IR machines and crack melters. In those 11 years, I’ve found Cliff to be the best of the best, working as a partner to my business instead of a salesman. He and all of the people I’ve had dealings with at Keizer Morris have been nothing but honest, helpful and truly interested in doing what’s best for their customers. It’s tough to find that level of commitment anymore.
