Webasto C81 – R BlueCool C-Series Chiller – 81,000 BTU’s – 230V

Description

Mid-to-large yachts with three or more independent cabins that need serious central cooling capacity without reaching the C-Series’ largest tier have a strong option in the Webasto C81-R, delivering 81,000 BTU/h of central chiller cooling with the same multi-stage flexibility as its larger siblings.

This webasto chiller multi stage unit can be configured across 1 to 4 stages depending on the vessel’s zone count and load variability, giving installers real flexibility to match the system to the boat rather than forcing a one-size-fits-all central plant onto every layout.

Key Features of the Webasto C81-R Chiller

This central chilled water yacht system brings the full C-Series feature set to a mid-capacity tier, suited for yachts that have outgrown smaller chillers but don’t need the full 108,000 BTU/h of the largest model in the range.

• 1, 2, 3, or 4-stage system configuration for matching output to variable cooling demands
• BlueCool Expert Tool enables remote diagnostics and troubleshooting from anywhere via USB cable and Wi-Fi
• Compressor noise reduced by up to 25% compared to previous generations
• Continuous cooling capacity maintained even in tropical operating conditions
• Cooling and heating via reverse cycle function included as standard

Webasto C81-R Technical Specifications

These figures come from Webasto’s official spec sheet for part number WBCL1207004D. As with other Webasto chillers in this range, the page title correctly identifies this as “C81 R” while the body description text refers to it as “C81 M” — confirming the part number directly with Webasto or CTM is a reasonable step given this naming pattern.

Why Choose the Webasto C81-R

This unit carries Webasto’s standard 2-year warranty. Note that the locked rotor amperage (54A) is identical to the larger C108-Q model despite the lower running current — a detail worth confirming with Webasto if you’re sizing a soft starter or backup power system, since it may reflect the same compressor platform shared across both capacity tiers.

What to Know Before Installing

• This chiller requires separately specified air handlers (Webasto’s A-Series) distributed to each independent zone
• The 3 x 20A max circuit breaker spec reflects the multi-stage compressor configuration — plan your electrical panel accordingly
• Ships via freight given the 308 lb weight; commercial delivery address required
• Professional installation and electrical planning is strongly recommended at this capacity
