Double tap

When sourcing a double tap tower or dispenser, prioritize 304-grade stainless steel construction for all components that come into contact with the beverage to prevent metallic off-flavors and corrosion. Ensure the system features internal insulation (typically high-density foam) to maintain temperature consistency and prevent condensation. For the faucets, look for forward-sealing designs which are more hygienic and prevent the internal mechanism from sticking due to dried sugars.

You must choose between air-cooled and glycol-cooled systems. Air-cooled systems are economically feasible for short-run setups (where the keg is directly beneath the tap), while glycol-cooled systems are essential for long-draw installations to ensure the beer stays cold from the cold room to the faucet. Verify that the cooling lines are pre-installed and pressure-tested by the supplier to avoid leaks during onsite assembly.

For the US market, NSF/ANSI Standard 18 (Manual Food and Beverage Dispensing Equipment) is critical to ensure food safety. For European markets, components must adhere to EC 1935/2004 regarding materials intended to come into contact with food. If the double tap is part of an electronic kegerator, ensure the unit carries UL, ETL, or CE certification for electrical safety and refrigerant compliance (e.g., R600a or R290 eco-friendly refrigerants).

Double tap systems are ideal for commercial bars, craft breweries, and home 'man caves' where space is limited but variety is desired. They allow for the simultaneous dispensing of two different beverage types, such as a lager and an IPA, or even non-alcoholic options like nitro cold brew coffee and kombucha, provided the seals are compatible with high-acidity liquids.

Draft towers are prone to denting and scratching. Insist that the supplier uses custom-molded foam packaging and double-walled corrugated boxes. For bulk orders, products should be palletized and shrink-wrapped to prevent shifting. Request pre-shipment inspection photos showing the internal padding and the final sealed crate.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for spare part kits (extra O-rings, washers, and springs) to be included at no extra cost, as these are vital for maintenance. Ask for a tiered pricing structure where the price drops by 10-15% once your cumulative annual volume reaches a certain threshold.

Utilize Secured Trading services provided by Made-in-China.com to ensure payment is only released upon confirmation of shipment. For large-scale commercial projects, hire a third-party inspector (like SGS or Intertek) to perform a 'Functionality Test' to check for gas leaks and flow rate consistency before the balance payment is made.

If the double tap system includes CO2 tanks, they are classified as Dangerous Goods (Class 2.2), which significantly increases shipping costs and requires specialized documentation. It is often more cost-effective to source the tanks locally and only import the stainless steel towers, faucets, and regulators from the overseas supplier.
