Hotsy HSS / HSDS Series

The engine and the burner both run on diesel, so you carry one fuel. A Tier IV Kubota diesel and a 12V Wayne burner on a skid, 5.0 to 9.5 GPM at 2,500 to 3,500 PSI, with two 25-gallon cross-linked fuel tanks. HSDS models swap in a heavier Hawk pump that runs at lower RPM.

What are you cleaning?

Tell us the job in your own words. A person at the counter calls you and starts with the problem. Nobody pitches a machine until we understand the job.

(818) 252-0706

How do we reach you? A phone or an email is enough.
A few more questions (optional)
A dead burner, a citation, a bid due Friday. Your words.
Downtime, labor, a lost bid. A rough idea is fine.
Brand, model, age if you know it.

Here's what happens next: The Pacoima counter calls you within one business hour. The call is 15 minutes. We ask what's going wrong, how you plan to pay, and who else weighs in. At the end we set a next step, or tell you straight that we're not the right shop. Nobody pitches anything until we understand the job.
