To start the process, complete a a quote form or call (800) 952-0121 or (262) 548-8900 and ask for Customer Service.

What materials are used in Hydroheaters?
The standard material for Hydroheaters is grade 316 stainless steel. Other metallurgies are available based on requirements for corrosiveness, abrasiveness, or other conditions that may require a variance from our standard materials. we can use 317L, Hastelloy, 254 SMO, up to AL6XN

Are Hydro-Thermal products ASME certified?

They are designed per ASME code, but are not certified. They can be certified upon special request.

Can your products be used to heat abrasive fluids?

The Hydroheater is very robust and reliable, and can be further enhanced as needed for heating abrasive fluids. For many applications, a weld overlay and enriched material in key areas is sufficient. Some applications such as slurries with sand content require additional overlays outside the basic weld overlay. This technique has greatly increased the heater’s internal component lifespan. Other fluids have required more extensive modifications. In oil sands froth heating applications, for example, a combination of a weld overlay as well as the use of hard, abrasive resistant materials is recommended. For specific requirements for your application, please contact Hydro-Thermal directly.

What types of media can a Hydroheater heat?
A Hydro-Thermal Hydroheater can heat a diverse array of fluids, from water to heavy, viscous slurries. Based on the type of heater you choose we can heat tomato paste, medium consistency pulp stock or higher solids content.

We also offer options that utilize low shear flow. This makes it ideal for food slurries with high solid contents where viscosity, chunk size, and overall integrity of the product must be maintained.

If the media you want to heat can accept steam, this is your solution.

What is Direct Steam Technology (DSI)?

Ideal for heating liquids and slurries over a wide range of viscosities and solid contents to precise temperatures.  More information.

How long have Hydroheaters been around?
The technology behind direct steam injection was developed in 1911. Inventors John White and Roy Miller patented heating equipment using steam to precisely control water temperature in 1927. Manufacturing industrialist, Harry Schauer invented the Hydroheater in 1934 for use in a paper mill in Wisconsin.

Today, more than 80 years after the Hydroheater was invented, Hydro-Thermal has taken the technology and expanded its application across diverse industries.

How do I request a quote?
Unlike heat exchangers, kettles or spargers, the Hydroheater is engineered specifically for your process conditions and unique application. We need to know a few things about your conditions, such as temperature range, steam pressure, and flow rates to size a heater specifically for you.

How do I identify the model number and/or serial number of my heater? 
To locate these numbers, first look at the heater itself. There you will find a Hydro-Thermal name plate with the model number and serial number engraved on it. Do not take the numbers off the actuator as those are not the Hydro-Thermal identifiers.

How do I request a field service technician to help maintain my heater or heating system? 
For standard field service, please use this form and a member of our team will be in touch.

Please call us at 800.952.0121 for urgent matters. If the issue is outside of normal business hours, please listen to the prompt on the after hours message for “Emergency Service.”

 

How often do I need to perform preventative maintenance on my heater?

Proper care of your Hydroheater will save time, money, and prevent unscheduled shutdowns. Whether you want to maintain your heater yourself or have Hydro-Thermal service it for you, we have options to keep your system running at optimal performance. Maintenance options
