Ecosoft RO drinking vending machine KA-250

The KA-250 vending machine is intended for purification and pouring of water into consumer bottles. It represents the ready-to-use module consisting of several functional units:

  • The water purification unit includes 9 consecutive stages: reduction of sediments, of chlorine with activated carbon, of water colour, water softening, removal of up to 99.8% of all impurities with the reverse osmosis membrane, adjustment of water pH, improvement of taste and odour, remineralization and UV disinfection.
  • The water pouring unit is a terminal for placing and filling the customer bottles with water, volumes 0.5 to 18.9 L.
  • The payment unit is presented by the bill acceptor, coin acceptor and magnetic card reader.
  • The telemetry unit, the key component of which is a multifunction controller with GSM/GPSR module. Provides the following operations: control of the reverse osmosis system operation and pouring process, blocking of the operation in emergency situations, display of warning and emergency messages, remote transmission of the emergency messages by SMS.

Key advantages

  • Quick start - start earning in 3 weeks
  • Independency - the machine gains profit 24/7 and does not require constant control
  • High profitability - the cost of 1 litre of water is 3 times lower than alternatives
  • Quickly pays off - the average return on investment period is 8-12 months
  • Maintenance - our network of service centres provides technical support in all the regions of the country
  • Stable efficiency of operation provided by the Dow Filmtec™ membranes (USA)
  • Remote control - GSM/GPRS module provides monitoring by Internet
  • Anti-vandal protection - housing made of durable material and shock-resistant control panel
  • Compact - the minimum rent required, since only 1 m2 of space is sufficient for the machine
  • Quality guarantee confirmed by international CE and ISO certificates

The vending machine is intended for cold water only. Maintenance and monitoring of its operation should be carried out by qualified service centre personnel. The maintenance procedure includes regular replacement of elements, replenishment of antiscalant and salts for remineralization.
