CDR DLX 25L (Horizontal) Specifications, Features & Compatibility Guide

PU Foam insulation in the CDR DLX 25L (Horizontal) is an engineering choice that minimizes standing heat loss, reducing reheat frequency and directly contributing to the 4 Star rating compliance. The 2 kWkW Copper heating element provides the thermal wattage required to heat the tank within acceptable timeframes while maintaining element longevity under repeated thermal cycling. Glass-lined tank technology involves applying a vitreous enamel coating to the inner steel surface at high temperatures, fusing the glass permanently. This creates a chemically inert barrier that no dissolved mineral can penetrate, solving the primary failure mode of budget geysers in Indian hard-water conditions. Safety architecture in the CDR DLX 25L (Horizontal) is built around 5 independent protection mechanisms: Dry-Heat Protection, Pressure Relief Valve, Thermal Cut-Out, Anti-Scalding, Over-Temperature Cut-Out. This layered approach ensures no single point of failure can lead to a hazardous outcome, which is critical for unattended residential operation. The Mechanical thermostat controls the heating cycle within a 25-75 °C°C range, maintaining consistent output temperatures through daily usage patterns. With a 0.5-8 bar pressure rating, the tank and valve assembly are stress-tested to handle the peak pump pressures in modern multi-storey residential buildings, where line pressure routinely exceeds the tolerance of standard geysers.
