Climate Controlled Cabinets

Medication, Saline and Other Storage Needs

Mermaid Manufacturing began making Medi-Kool's a little over 10 years ago.  We are the originator's of the climate controlled medication storage solution.

All of our units come standard with a Medi-Kool Digital Control Board.  Detailed information is available under 'Control Board Instructions' and 'MK Control Board' (to your left)

Medi-Kool's are compressor based.  We carry a FIVE year warranty on all of our compressors alone.  We do have a detailed warranty that we would like you to be familiar with (in the catalog   

To date (2014), we still have units operating in the field that go back to 2003 (our original plastic units that we've discontinued).  Think of Medi-Kool the same way as your refrigerator (except that it heats) and is designed, built and shipped to be upright at all times.     

Our units are made from high quality stainless steel - in fact, that's what the 'SS' stands for in our model numbers.  Not only is stainless steel durable, but it is also extremely STERILE, which we know is important in the world of First Responders.

Regardless of the Medi-Kool product you choose, your medication, narcotics, saline or other fluids will be continuously monitored and temperature controlled at any given moment.  Powered by a 12V, low amp (5.7) draw unit, our heating and cooling system provides the climate control you need.  Each unit uses a refrigeration and heating system designed to change the core temperature substantially off ambient.  

The standard Medi-Kool SS comes equipped with a Medeco lock - these locks cannot be picked and keys cannot be duplicated.  The White House and countless other Federal Buildings around the country use these locks.  Two keys are included with the order of any unit and additional keys can be ordered for an extra charge.    

We do offer other locking options that include audit trail, electronic locks or just a basic knob if you prefer not having a lock.  Please click on 'Lock Options' for more information.

The smaller units come in MICRO DEPTH or SALINE DEPTH.  We designed these options at the request of our customers.  Saline Depth is deeper than our Micro Depth for additional depth storage.  It all depends on how much room you have if you're doing a remount, or how much room to acclimate if building from spec.  Our dimensions are listed in our catalog and on our products (to your left).

Please let us know what specific dimensions you need if you do not see them here.

Our units are designed to maintain temperatures between 35 degrees F, up to 110 degrees F.  They will stretch a little further, but we don't recommend freezing or overheating your drugs.   

The MK Dual Temp Unit is designed to maintain two separate temperatures within one unit.  Each section is controlled by its own compressor, climate control board and thermostat.  Perfect for saline storage on one side and drug storage on the other.  Over the last few years we have seriously looked at the issues of drug storage in emergency vehicles and the temperature control on drug efficiency.

All of our units (with the exception of the MK PELICAN) will reduce the internal cabinet temperature nearly 50 degrees of ambient!  Certain factors may alter these numbers IE: outside temperature, ventilation, and air con usage. The MK PELICAN will reduce temperature 25-35 degrees off ambient.

For the States that have currently implemented the Induced Hypothermia Protocol (also known as Theraputic Hypothermia), our units will meet or exceed all the current regulatory requirements. 

Medi-Kool units are a simple and efficient solution to any climate control need.

A single unit with two sections. Temperatures in each section can be as low as 32 degrees F or as high as 109 degrees F. Compressors can be mounted to the rear, right, left or on top of the unit. No door hinge options.


A single unit with two sections.  Temperatures in each section can be as low as 32 degrees F or as high as 109 degrees F.  Compressors can be mounted to the rear, right, or left of the unit. Doors can be hinged right or left.


We have developed the smallest, most efficient refrigeration unit available. This unit does have a lightweight compressor option for flight use. Compressors can be mounted to the rear, right, or left of the unit. Doors can be hinged right or left. You can also order this as a refrigeration only unit.


This is the same unit as the MK-Micro horizontal unit, but assembled on it's side for different dimension requirements.  Compressors can be mounted to the rear, right, or left of the unit.  Doors can be hinged right or left.


Our latest design, the MK Chief, was specifically designed to fit into the EMS / Fire Chief Vehicles - this is the same unit as the MK Micro Vertical (Micro Depth), but mounted as a stand alone unit.  It can be hinged to the right or left and the compressor is mounted on the left.  It is designed to be hard mounted to the deck in the back of an SUV and hard-wired into the vehicles electrical system.  It is not a portable unit.


The Medi-Kool Saline SS was developed to supply a low cost way to store saline for Hypothermia-Inducement, also known as Theraputic Hypothermia.  This unit is designed to operate at 34 to 38 degrees.  You can also order this as a climate controlled unit.  Doors can be hinged to lift up or drop down.
