UWLD - Heating Solutions - Heat Controller - Underwater Light Dude
Heat Controller
Plug it into your heated drysuit under garments, and it keeps you toasty warm. It's that simple.
Stacking Cap - Now you can have both heat and light on the same battery canister. The stacking cap allows a second cap to be stacked on top of this canister cap. Comes with a blanking cap to use stand alone.
Description
Main Features
LED battery status indication around the Piezo switch. Eliminates guessing battery charge and extends the life of the battery by only charging when needed.
Constant heat output from start to finish of battery
Heat does not decrease with battery level; very important for optimal decompression
5 heat levels for range of comfort in water of -3c to 20c (23F° – 68°F)
Piezo switch control for both on/off & changing heat levels
Eliminates the high failure rate of boot switches
Mechanical switch does not have to be toggled to adjust levels
LED indicator for battery status indication (high/green, medium/yellow, low/red), power on/off, & heat level setting
Can be used independently or with lights on the same battery
Small, compact & light weight design
Compatibility
Compatible with all UWLD Latchless Batteries
Comes standard with the stack cap for the Latchless Battery
Stack cap allows the controller to be added or removed with ease
Industry standard wetmate E/O connection
Supports all 12v heated under garments
Incompatible with lights heads run downstream of the controller
Incompatible with non-UWLD battery canisters
The Science
Research has shown optimal decompression occurs when warm
The body may be cool on descent, but should be warm on ascent
from discusses Thermal Physiology and how temperature effects decompression in  &
Warm is 36C (96°F) | Cool is 27C (81°F)
Being warm at the beginning of the dive increases the uptake of inert gas
Being cold at decompression confounds decompression
Why UWLD?
Leverage existing investment in light and batteries
Advanced technology ensures consistent heat at the most crucial time, the end of the dive. Traditional solutions offer only 75% of heat at bottom low end of the battery.
Double O-Ring Seal
LED feedback removes guessing of set heat levels
LED battery level indication
Battery Burn Time
The controller runs slightly above undergarments rated wattage on high
To calculate burn times, UWLD suggest that 110% of wattage be used. If a diver has a 60W vest, they should calculate burn time for 66W for the high setting.
Each level drops the power consumption by 20%; for a 60w vest: Level 4 = 53W; Level 3 = 40w, Level 2 = 26.5W, and Level 1 = 13W.
With a light, add the light and vest wattage then divide by canister rating:
30W (LD-35) 60W vest(X 110%)= 96W /160Wh (canister rating)
Both on high yields 1.66 hours on a tall canister
Light on high, vest on low yields 3.7 hours on a tall canister
