Magnetic Insulation is easy and quick to install.
It works well in the cold storage business with a payback of three to six years.
At colder temperatures, the payback is faster. HIG software tools find the payback in dollars and time so that operators know if MI Grade insulation meets investment return objectives for their facility.
MI Grade insulation, on the outside, looks like any other backed insulation. Inside the insulation are powerful magnets with long life spans. Hydra Industries Group intellectual property (Patents and Patents Pending) secures powerful magnets to the foam boards. The lifespan of the magnets is long. The engineers say that 95% of the holding force is intact after 200 years.
Pre-cut to fit at the fabricators, Magnetic Insulation snaps into place with little or no interruption to ongoing operations. If requested, HIG manages the install for a hassle-free experience.

You would like a sample of MI Grade Insulation
HIG to run a payback analysis for your facility.
Hydra adjusts the parameters of its software tool to fit your property and location. Next, we run the program Dr. Wang created for the payback time and dollar savings.
Hydra Industries Group’s vendors and suppliers have facilities across North America which means that freight costs and delivery times are quick.
Please note that the colder the operating temperature, the greater the return.
Please see the example in the charts below.
How did we calculate the payback period?
Dr. Shuping Wang annotated his code parameters for a better understanding of the tool HIG uses to calculate best thickness and payback times.
A = 10000.0; %total area [ft^2]
A = A*0.092903; %ft^2 to m^2
k_ins = 0.025; %thermal conductivity of additional insulation [W/m/K]
k_1 = 0.034; %effective thermal conductivity of the existing wall[W/m/K]
%Typical insulation conductivity in [W/m/K]
%Polyisocyanurate/PU foam board 0.025
%Expanded polystyrene (EPS) 0.036
%Extruded polystyrene (XPS) 0.034
%Glass mineral wool 0.035
delta_1 = 3; %effective existing wall thickness [inch]
delta_1 = delta_1*0.0254; %[inch to m]
c_e = 0.1274; %electricity cost [dollar/kWh]
r = 0.05; %electricity discount price rate, e.g., 1 dollar money next year is only worth 1-r under present year
d = 0.05; %electricity normal price increase rate
N = 20; %life cycle period years
T_o_des = 93; %Outside temperature used for AC design [degF]
T_o_des = (T_o_des – 32)/1.8; %F to C
h_o = 25; %Outside convective heat transfer coefficient [W/m^2/K]
h_i = 8; %inside convective heat transfer coefficient [W/m^2/K]
COP = 2.9; %COP for the AC at the design outside temperature
C_A = 4*1.5; %Cost of additional insulation per volume [dollar/ft^3]
C_A = C_A/0.0283168; %[dollar/m^3]
%assuming the price of magnetized insulation is 150% of the regular
%note that this will be your price per volume.
O_h = 365*24; %Operation hours
The program calculates optimum thickness too. Magnetic insulation comes in 2,4,6,8” thickness choices. $70,000 is the savings for the yellow line case where the outside temperature averages 70° F.
