Lighting Systems
The SZL230-340 is a patent pending lighting system designed for operating
temperatures down to -40°C
The SZL lighting system comprised of two core
components:
-
Lightsource (located in the roof void)
-
Light transmission conduit (LTC)
The SZL - Lightsources
-
There are
two lightsource options
-
A 230W
version delivering 18,876 lumens and a 340W version delivering 29,484 lumens
-
Designed to efficiently transmit the light into the LTC
-
Lamp has a 20,000 hour lamp life, generating 120 lumens per watt
-
Lamp warm up time of under 60 seconds.
-
A colour temperature of either 3000°K or 4200°K, with a colour rendering index of
Ra 90
The SZL - LTC
-
Designed to deliver maximum light (internal reflectivity of
greater than 98.5%) with
minimum thermal transfer, either by conduction, convection and very
little radiation in either direction of the LTC
-
Hermetically sealed into the insulation substrate between the
illuminated space and the roof void, thus allowing the light to enter the cold storage
space with minimum temperature transfer
-
The LTC protrudes only 6mm into the illuminated space and is manufactured
from polycarbonate and stainless steel
-
The unique way of delivering the
light into a space, with the SZL light-source mounted within the roof void,
means our lighting systems are extremely hygienic
The LTC
 
Above are various views through the LTC, showing the
extremely high
level of internal reflectivity along with the high efficiency or the anti
reflective coatings on both input and output windows.
