Discontinued Product Line

The Rite-Temp horizontal chiller series has been discontinued. Schematics and technical documentation remain available for existing units. A new product line — available in 1.5 to 10 ton configurations — is in development. Contact us for updates.

Horizontal Chiller Overview

Rite-Temp's horizontal water chillers featured a low-profile, flat design that made them uniquely suited for facilities with height restrictions or outdoor installations requiring wind resistance. The horizontal orientation lowered the center of gravity, providing stability in demanding environments.

Like all Rite-Temp equipment, horizontal chillers were manufactured to order at our Rogers, Arkansas facility — individually built to meet your exact cooling requirements, electrical specifications, and installation constraints.

  • Low-Profile Design — Fits in spaces where vertical clearance is limited.
  • Wind-Resistant — Stable, flat profile ideal for rooftop and outdoor installations.
  • Self-Contained — All components in one compact horizontal cabinet.
  • Air or Water-Cooled — Configurable for your specific installation environment.
  • Brazed-Plate Evaporator — Efficient heat exchange for rapid cooling response.
  • Custom Built — Each unit individually constructed to your specifications.

Horizontal Chiller FAQs

Are Rite-Temp horizontal chillers still available for purchase?+
No — the horizontal chiller line has been discontinued. A new product line in development will be available in 1.5 to 10 ton configurations. Contact us at 1.800.462.3120 or via our contact page for updates.
Why were horizontal chillers ideal for rooftop installations?+
The low-profile horizontal design kept the center of gravity low, making units more stable in high-wind rooftop environments. Their flat footprint also made them easier to fit through rooftop access hatches and into mechanical penthouses with restricted headroom.
Can I get schematics for my existing horizontal chiller?+
Yes. Electrical schematics for all horizontal models are available as free PDF downloads on our schematics page. Our technical team is also available Mon–Fri, 7:00am–4:00pm CT to answer service and maintenance questions at 1.800.462.3120.
What is replacing the horizontal chiller line?+
Rite-Temp is developing a next-generation chiller product line in partnership with a leading refrigeration manufacturer. The new lineup will be available in 1.5 to 10 ton configurations. Call 1.800.462.3120 or email Chillers@RiteTemp.com for the latest updates.
