TEST MARKETING NOT/FICA TION FOR R290 WATERCOOLERS UNDER SNAP 

PROGRAM IN THE USA (California) 

Dear Sirs, 

Following my meeting with Mr Gerald Wozniak of the EPA during the event ATMOsphere America 

2015 held in Atlanta in June 2015, BLUPURA Italy and BLUPURA USA Inc. hereby submit a 

notification for test marketing of our watercooler models with natural refrigerants R290 in the 

USA. 

BLUPURA Italy was founded in 2008 by Mr Gianni Grottini and myself to manufacture mains fed 

watercooler units. Because of our commitment to protect the environment and to distinguish 

ourselves from other mpnufacturers of watercoolers, we immediately chose to use natural 

refrigerant propane in our models. BLUPURA Italy has been manufacturing watercoolers with R290 

(propane) since 2008 to supply all European countries as well as other regions, such as South 

Africa and Australia. Until today around 12.000 watercoolers have been sold. The hydrocarbonbased watercoolers have been manufactured following the European standards and the 

refrigerant charge for each model is below 150g. 

BLUPURA USA Inc. was founded in 2014, with a sales office and a warehouse in Miami, as a result 

of the success in Europe and to better and faster supply equipment t? North American customers. 

Watercoolers supplied for the North American market currently use R134a, however, our 

customers, especially in. t he Silicon Valley area, are increasingly demanding watercoolers based on 

natural refrigerant R290, which are climate friendly alternative to conventional R134a technology. 

As R290 is not yet approved for use in watercoolers in the USA, BLUPURA submits the test 

marketing notificaifon with the following specifications: 

• Name of the alternative: R290, propane 

• Volume used in test marketing: 3.000 lbs I year (which translates to around 10.000 R290 

watercoolers I year)

R290 watercoolers were tested by the independent laboratory INTERTEK in 2009. You can find the 

test on REFRIGERANT LEAK SIMULATION attached to this notification. The findings of the test 

point out that "this appliance has been identified as complying with t~e definition of clause 22.107 

of EN 60335-2-24 for "Compression-type appliances with protected cooling system which uses 

flammable refrigerant" in this case Propane". It is important to note that a great majority of our 

models are approved by INTERTEK following the AINSI I UL 399 and we are in the process for 

getting this approval for (!II the models . 

.. 

BLUPURA has the technology, necessary skills, experience, and the (European} certification, to 

supply R290 watercoolers for the US market. We therefore kindly request you to accept this 

notification and &r?nt BLUPURA test marketing period for watercoolers using pro.
