Case 25V17 – Genuine OEM R-454B Dedicated Horizontal Evaporator Coil (4 to 5 Ton, CK40HT)

The Case 25V17 (Model CK40HT-51/61C-71) is a next-generation Genuine OEM Dedicated Evaporator Coil engineered specifically for the transition to R-454B low-GWP refrigerant. Designed for high-tonnage residential and light commercial applications, this 4 to 5-ton coil serves as the indoor heat exchanger, absorbing heat from your home’s air while seamlessly integrating with the latest high-efficiency outdoor condensing units.

Technical Performance:

Built for horizontal installation, this coil features an all-aluminum construction to eliminate the risk of formicary corrosion, a common cause of leaks in traditional copper-tube coils. The CK40HT is factory-tested and specifically orifice-balanced for R-454B, ensuring optimal refrigerant flow and pressure management. Its cased design provides structural rigidity and a simplified "slip-fit" connection to standard ductwork, maintaining peak thermal transfer across its expansive surface area.

Key Features and Function:

Feature 1: R-454B Optimized Design: Specifically engineered for the unique pressure and thermodynamic properties of R-454B refrigerant.
Feature 2: Advanced Aluminum Casing: High-grade aluminum fins and tubes offer superior corrosion resistance and long-term durability.
Feature 3: Horizontal Airflow Configuration: Ideal for attic or crawlspace installations where height is restricted and horizontal ducting is required.
Feature 4: High-Tonnage Capacity: Versatile 4 to 5-ton rating allows for precision matching with high-capacity outdoor heat pumps or AC units.

Product Details and Key Specifications:

Catalog Number: 25V17
Model/Part Number: CK40HT-51/61C-71
Manufacturer: Case / Allied Air (Genuine OEM)
Capacity: 4.0 to 5.0 Tons
Refrigerant Type: R-454B (Dedicated)
Configuration: Horizontal Cased Coil
Material: All-Aluminum Tube and Fin
Shipping Weight: 68.0 lbs

🛠️ HVAC Depot Pro Tip: The "Leveling" Secret

When installing the CK40HT horizontally, ensure the unit is pitched slightly (about 1/4 inch) toward the primary drain pan connection. R-454B systems often run colder evaporator temperatures; proper pitching prevents condensate from "bridging" across the fins and blowing into your supply ductwork, which can cause water damage and mold growth.

OEM Numbers: 25V1701, CK40HT-51/61C, CK40HT

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Verified Buyer

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.
