Walkin Freezers & Coolers featuring the Tafco E (Eco) Series Commercial Refrigeration System
Walkin Freezers and Coolers with theTafco E Series Commercial Regrigeration System are the most energy efficient, for the capital expenditure, of the Tafco Refrigeration Systems. Customers will realize
the quickest return on investment with the purchase of this system.
The Tafco Eco (E) Series is our most energy efficient system for your money. The Tafco Eco Series comes with a 1 year warranty on parts and 60 days on labor. The system incorporates a number of features which enhance walkin freezer and cooler performance, provide energy savings over our Tafco Value Series, and increase reliability, thus saving you money. This is done by a design that eliminates the need for a refrigerant receiver by providing built-in storage capacity in the condenser section of the condensing unit. This small change allows for the addition of new features that are not possible in the traditional refrigeration systems. It actually gives the same size condenser up to 20% more capability by providing a potential 50% increase in condenser surface. This feature increases compressor size and lower operating pressure provides an initial energy savings of up to 10%. This feature provides 30% in additional energy savings during low ambient conditions. Additionally, it also supplies sub-cooled liquid refrigerant to the expansion valve to maintain optimum valve performance.
Walkin Freezers and Coolers with E (Eco) Series refrigeration systems can offer energy savings of up to 40% over conventional walkin freezer and cooler refrigeration systems (see graph below). Tafco E Series systems require up to 20% less refrigerant to operate, while maintaining continuous peak performance. In typical systems, the receiver, its outlet valve, and piping will create bubbles in the sight-glass due to the pressure drop they create. By eliminating the receiver and its piping components, the clearing of the sight-glass occurs much faster and with less refrigerant. The E Series sight-glass signals when the ideal charge has been attained, thus saving refrigerant and its cost.
