Koolspace™ cooling units are designed to sit in a hole in the wall, roughly equal size to the cooling unit itself.  KoolR Plus vent directly to and an adjacent air-conditioned interior space. The KoolR units can not mount in the ceiling or on the floor.  They are not designed to work with ductwork nor be installed directly to the outside.  These are interior, through the wall units only. 

Ideally, koolR/KoolRPlus Magnum units should be installed above a door as they need air circulation around and below the unit.  If your walls are thicker than 6 1/2" then we also have 8" screws available. please specify at time of ordering.  

The Magnums blows the cool air down and to the sides.   It needs to be installed a minimum of 5" from the ceiling and have 10" to either side of it.  It needs 2ft below of unobstructed air flow which is why is it ideally installed above a door.  The koolR is NOT meant to be ducted nor to be enclosed in any way.  

The wine cellar cooling units conveniently monitor the temperature inside your wine cellar, with digital display showing in adjacent room.

Although the cooling units are rated for various size rooms, the thermal load may require a larger sized cooling unit.  Thermal load may be affected by glass in the cellar, room positioning or other factors.  Please let a Rosehill Wine Cellar rep make some suggestions for you if needed. 

Warranty is NOT covered for commercial use of the KoolR Magnum.  

The KoolR Magnum is NOT designed to go into cabinets, this unit is meant for wine rooms with open airflow around the unit.

What's new about the KoolR units...

Quick mounting, reduced vibration and thickest epoxied copper in the industry.

How are they installed?...

koolR™ cooling units need to vent through a wall to an adjacent climate controlled interior room.
They are not designed to go through the ceiling, floor or ductwork or directly to the outside.
The are also not designed to be installed in a small cabinet as these units need clearance to the front, sides and bottom for air circulation.

Clearing up some misconceptions about Koolspace...

  • Injection molded clamshell design - sleek and modern - superior engineering
  • Quietest wall mounted cooling units on the market because of the fan technology.

What Else you Should Know...

A wine cooling unit is a major investment and the most important component of your wine cellar. Before you buy, ask a few simple questions:

What is the true power rating?

Compressors are sized according to the BTU rating, however the TRUE cooling power of a unit has to do with the size of the coils and the fans. koolR™ has been tested in against a series of leading competitors with same size compressor. With koolR's™ larger coils and greater airflow - there really was no contest!

What about the key components?

Koolspace spends a lot more on components like Embraco compressors, hi-flow axial fans and stainless steel. Others save a bundle with offshore parts, then they charge more for their products!

What about noise?

koolR™ is engineered for quiet, with an exclusive Acoustic Isolation Chamber, koolR™ produces far less noise, with much greater airflow than others.

Are digital controls necessary?

Absolutely! Electronic controls maximize efficiency as well as guarantee longer life and our controls are the world's smallest and most advanced. Digital controls with LED are standard, not an upgrade!

The digital display is on the warm side of the cellar. Meaning you cannot read the digital display when you are inside the cellar, you need to stand in the adjacent room and look at the back of the unit. This is actually very desirable as you'll be able to see temperature within the cellar without needing to open the door to check.

The digital temperature range of the koolR is 52ºF (11ºC) Max. 64ºF (18ºC)

What about electrical needs?

All koolR units plug into standard North American household outlet. Dedicated preferred. Electrical outlet should be inside the cellar.

Is the unit certified?

Shocking, but most wine cooling units are not certified. Every koolR™ is CSA,UL C and CE-Certified to the most rigorous international standards.

What about vibration isolation?

Only the koolR™ line of wine cellar cooling unit, with their multi-point isolation, can claim to eliminate the vibration created by all of the major components as well as the exterior housing.

What happens to the condensate?

Some systems use manual electric condensate evaporators, which waste energy and efficiency, to boil away their excessive condensation. KoolR™ uses the condensate to cool the system and increase efficiency. This saves energy and maintains higher humidity.

What about corrosion-resistance?

Aging wines generate acetic acid, which can shorten the life of your coils. koolR's™ hermetically-sealed controller, E-coated coils and cabinet give corrosion protection like no other.

What about price?

Compare, compare, compare. Feature for feature, dollar for dollar, compare koolR™ with any other wine cooling unit available. KoolR™ has a refined design, more features and better value than any other.

What if I have thicker walls? 

8" screws are also available for the KoolR Magnum. Please specify at time of ordering.

Each koolR™ wine cellar cooling unit features:

  • Multi-level vibration suppression system
  • Superior energy efficiency
  • All digital temperature sensing
  • Microprocessor controls
  • Super-bright LED display
  • Excess humidity warning
  • High temperature alarm - with audible & visual signals
  • Pop-in mounting

    Poor reliability

    Posted by Rolando Roti on 29th Mar 2023

    This is the third unit I’ve purchased, and I find it only lasts me from 18 months to 24 months the most.

Interesting As Well
