1.8 cu.ft. Countertop Refrigerator

Frequently Asked Questions

How does this refrigeration technology work?

TSG205 uses a non-toxic, non-hazardous refrigerant 
embedded in the walls to absorb and channel heat energy to 
an internal, solid-state heat pump; the component that 
replaces the compressor in a typical refrigerator. The heat 
pump cools the refrigerant material when it channels the heat 
energy out of the system and into the ambient environment. 

How reliable is the system?

Strenuous testing protocols were used to develop 
confidence in the construction and system design of our 
refrigerator. Our studies indicate at least a 10-year life 
expectancy based on these stringent test protocols.

What is the product warranty?

2-year product warranty on parts and labor with 5 years on 
the solid-state heat pump.

Is the power cord healthcare/NEMA approved?

Yes, it is a National Electrical Manufacturers Association 
(NEMA) approved plug (indicated by a green dot on the 
cable).

Why is there a battery?

The included internal, standard-sized, non-rechargeable 
lithium CR123A battery provides continuous power to internal 
data logging.

How long before I can use the product?

In a normal ambient environment, your refrigerator should pull 
down to the target set point within a couple of hours. It is 
common industry practice to monitor the unit over 48 hours to 
ensure it is holding the set point temperature. 

Why is there condensation building up on the walls? 

Condensation is completely normal in a cold wall refrigeration 
system. Condensation occurs when humid air cools when in 
contact with the cold walls and excess water vapor 
condenses on the walls as droplets. There is an out-of-sight 
system that collects and evaporates the excess runoff. You 
may see excess condensation during the initial cool down 
period and this can be wiped down. If persistent 
condensation build up occurs, we recommend replacing the 
provided desiccant bag with a new one.

Where can I find the serial number? 

You can find your important and specific product information 
by accessing the control interface. 

(Main Menu -> Tools 

-> Info)

The product Serial Number can also be found on the shipping 
label (on the shipping box) and on the product label (on the 
back of the unit behind the rear cover).

Is the unit calibrated? Can I calibrate my refrigerator? 

The refrigerator does not come pre-calibrated to National 
Institute of Standards and Technology (

NIST

) standards. To 

ensure proper calibration in the working environment, both 
the air & glycol sensors can be calibrated. See the Calibration 
section for instructions.

What kind of refrigerator maintenance is required?

Occasionally you will want to check the external fans for dust 
build up and clean as necessary. Otherwise there is no 
maintenance required to keep the system working at peak 
performance.

May the units be placed in a Pyxis cabinet? 

As with any electrical or mechanical system, heat 
accumulation in a closed environment can impact the cooling 
performance of the refrigerator. We recommend adequate 
ventilation in the back wall of the cabinet to dissipate heat 
outside of the cabinet.
