Total Ownership Cost: Selecting the Right Clean Air Project Options

Analyzing Total Ownership Costs: Selecting the Right Clean Air Project Option

In the previous couple of blogs, we discussed planning and designing clean air systems, including choosing the right filtration technology and fan selection. Total ownership cost is a crucial parameter to consider, including filter technology, air flow capacity, running costs, filter replacement costs, blower capacity, and ducting length.

What is the total ownership cost?

Total ownership coat, a management accounting concept, helps determine the direct and indirect costs of a product or service over the long term to arrive at the correct decision while making decisions.

What is the total ownership cost of a clean-air system?

Total ownership cost for a clean air system consists of some parameters such as air flow capacity, filter efficiency, compliance with EMS, size of equipment, considered duct length, static pressure, blower capacity, cell configuration, total initial investment cost, running cost for 1 year, AMC charges per year, standby filter cell, replacement cost of the filter, any optional accessories, etc.

In short:

Total Ownership Cost concept for 3-5 years (installation cost + running cost + maintenance cost + replacement cost = Total Ownership Cost)

Consider a simple case study to illustrate this concept. A fume extraction system with a 45,000 CMH airflow capacity—three options based on different filtration technologies—is worked out.

Total Ownership Cost Scenario for

Electrostatic Precipitator Technology (ESP)

Cartridge Technology

Wet Scrubber Technology

You can read about the above 3 technologies in our previous blog article here.

Total Ownership Cost Structure

Parameters ESP Technology Cartridge Technology Wet type:Venturi Scrubber

Airflow Capacity 45000 CMH 45000 CMH 45000 CMH

Filtration Efficiency 95+/-2% for 0.5 micron and above particles It depends on media selection. Generally chosen cartridge: 99% for 1 micron or 0.5 micron for welding fumes 99% for 5 microns and 98% for 2 microns

Compliance with EMS Filtered air output is less than 5 ppm. Filtered air output is less than 5 ppm. Filtered air output is less than 5 ppm.

Size of Equipement Compact Larger than ESP system. The biggest of the three

Considered Duct Length Approx. 100 mtr. per system Approx. 100 mtr. per system Approx. 100 mtr. per system

Blower Capacity 50HP/37Kw 100HP/74.5Kw 150HP/112Kw

Total Initial (Basic) Investment Cost (Equipment, Ducting, and Installation) INR 60.16 lakh INR 76.31 lakh INR 104.81 lakh

Running Cost for 1 Year (considering 16 hours per day x 300 days and 10 Rs/unit) INR 17.76 lakh (per year) X 3 years = 53.28 lakh INR 35.76 lakh (per year) X 3 years = 107 lakh + compressed air charges INR 53.66 lakh (per year) X 3 years = 161 lakh + water charges

AMC Charges per Year (All Scope) Approx. Rs 6 lakh (for 12 visits per year) X 3 years = 18 lakh Approx. 1 lakh (for 4 visits per year) X 3 years = 3 lakh Approx. Rs 6 lakh (for 12 visits per year) X 3 years = 18 lakh

Replacement Cost Filter After 3 years, Rs 1.20 lakh for pre- and after filter replacement & After 5 years, Rs. 3 lakh for ESP filter refurbishment After 2 years, Rs 9.90 lakh N/A

Optional accessories like a VFD, PLC, motorized damper, spark trap, etc. INR 12.92 lakh INR 19.73 lakh INR 27.15 lakh

Total Ownership Cost for 3 Years 154.56 Lakh 215.94 Lakh 310.96 Lakh

Cost Breakdown Parameter-wise & Technology-wise:

Total Ownership Cost Structure

Cost Parameters Cost Of ESP Technology Cost Of Cartridge Technology Cost Of Wet type:Venturi Scrubber

Installation Cost 60.16 lakh 76.31 lakh 104.81 lakh

Running Cost 53.28 lakh 107 lakh 161 lakh

Maintenance Cost-AMC 18 lakh 3 lakh 18 lakh

Replacement Cost 1.2 lakh 9.9 lakh 0

Optional Cost 12.92 lakh 19.73 lakh 27.15 lakh

Total Ownership Cost for 3 Years 154.56 Lakh 215.94 Lakh 310.96 Lakh

Fig: Total ownership cost(Technology wise breakup)

Understandings from the above example:

As per the above example of total ownership cost calculation about the 3 technologies, we can conclude that the ESP technology is totally beneficial in the long run as per the costing, as the total cost is very low; it’s only 154.56 lakh as compared to cartridge technologies 215.94 lakh and wet scrubbers 310.96 lakh for the period of 3 years.

Key takeaways from the above example:

From the above example, you can see that the total cost of ownership of ESP technology is low as compared to the other two technologies.

The total cost of ownership consists of several parameters that are very important, including air flow, blower capacity, initial cost, filter cost, cost of ducting, etc.

The most important parameter of the clean air system is air flow calculation, so air flow rate is the most comparable factor to check which proposal is capable of solving your industrial indoor pollution problem.
