Paloma 28L Eco Max External (Commercial)
– PH-28CMX(SA)
External Continuous Flow Water Heater
The 28 l/m External unit is 6-star, energy rated, at 84% thermal efficiency. The Paloma 28 is able to deliver temperatures of up to 82⁰C and offers a host of other features and benefits (per below). This unit is wall-mounted, outside, where there is plenty of ventilation, guided by a registered gas installer.
These powerful units can be used in medium to large homes; a Paloma 28L can provide hot water for 2-3 bathrooms and 1-2 kitchens (dependent on installation)
Commercial Gas Water Heater
The 28 l/m commercial unit is ideal for larger commercial applications or where higher temperatures are required. Units can be electronically manifolded to increase capacity from 1 to 6 units by either manifolding 2 units with a Paloma EZ-Link for up to 56 l/min of hot water delivery, or up to 6 units using the MIC-6 system. The MIC-6 system is able to supply a large capacity of hot water while maintaining high energy efficiency in applications such as gyms, restaurants, breweries, hotels, hostels, hospitals, factories, ablution blocks, camps, etc. In these instances, the propriety ranking of each unit is rotated according to specific conditions, which allows for the equalisation of load amongst units. Until the load reaches 80% the master unit has priority and operates on its own, then the 2nd priority unit begins operating after that, the load will equalise among all the operating units. This system spreads the workload across units, creating redundancy and ensuring master-slave use.
All Paloma Units can be connected to temperature controllers however, in commercial applications where higher temperatures are required, this may not be applicable. Always refer to your qualified gas installer or the manual.
All Paloma appliances are available for use with either LPG or Natural Gas.
