When you run a selection, the software automatically calculates the required relief valve capacity and shell-side design pressure. For ammonia systems under the EU Pressure Equipment Directive (PED) or ASME BPVC Section VIII, having a printed selection report from official software acts as auditable documentation.

MyCom Selection Software sits at the intersection of precision and possibility — a tool designed to make the messy, human process of choosing the right candidate or solution feel intentional and even inspiring. At its core, it’s more than a checkbox-driven engine: it’s a decision companion that translates organizational priorities into measurable, comparable outcomes.
Think of it as an orchestra conductor. Data points are instruments: resumes, skill assessments, cultural-fit indicators, compensation expectations, and performance projections. MyCom’s algorithms arrange those instruments into harmonies and counterpoints so hiring teams can hear the full composition rather than individual notes. The software streamlines screening without flattening nuance, preserving the idiosyncrasies that often predict success while amplifying objective signals that reduce bias.
Where MyCom shines is in configurability. Organizations vary wildly — startups need growth potential and grit, enterprises prioritize reliability and cross-team collaboration, and research groups hunt for niche technical depth. A flexible weighting system lets decision-makers prioritize what matters now and re-tune as priorities evolve. That dynamism is liberating: it reframes selection from a static gatekeeping ritual into an iterative, strategic process.
There’s also a human-centered elegance to well-implemented selection software. Good interfaces surface trade-offs clearly: when you boost the weight on technical skill, what do you lose in cultural fit? When you demand rapid availability, which high-potential candidates might be filtered out? Those conversations foster better hiring outcomes because teams negotiate values consciously rather than rationalizing automated outputs after the fact.
Of course, bright promise comes with responsible guardrails. Transparency in scoring, explainable reasoning for recommendations, and audit trails are essential. Without them, powerful selection tools risk amplifying hidden biases or creating false confidence. The best systems pair statistical rigor with interpretability, offering both ranked suggestions and plain-language rationales that humans can contest and refine. The primary purpose of this software is to
Operationally, integration is key. A selection platform that talks to ATS systems, skills-assessment providers, calendar tools, and payroll systems reduces friction and keeps candidate experience smooth. Quick, respectful candidate communication — automated yet personalized — preserves employer brand while accelerating decisions.
Finally, imagine the downstream benefits when selection is done well: reduced turnover, faster onboarding, better team chemistry, and measurable performance gains. When selection becomes an intentional capability rather than a recurring pain point, organizations can invest energy in growth and innovation instead of firefighting hiring mistakes.
In short, MyCom Selection Software — when thoughtfully designed and responsibly deployed — can transform hiring into a strategic advantage: a blend of data, design, and human judgment that elevates both decisions and the people making them.
The primary purpose of this software is to determine the optimal compressor model, required motor horsepower, and performance data based on your specific refrigeration needs. It replaces the old paper "rating tables."
What it calculates:
While the interface varies slightly between the desktop client and the web-based portal (Mycom Navigator), the logic remains consistent.
Step 1: Define the Application Are you freezing (low temp), cooling (medium temp), or heat pumping? Choose the cycle type.
Step 2: Input Evaporating Conditions Enter the saturated suction temperature (SST) or pressure. Pro tip: Add 2-3 psi for suction line losses here.
Step 3: Input Condensing Conditions Enter the saturated discharge temperature (SDT). The software will ask for ambient conditions or fluid inlet temperatures if it is a packaged unit.
Step 4: Add Liquid Subcooling & Suction Superheat These are critical. If you are using a liquid economizer, check the "Economizer" box. The software instantly recalculates the 5-15% capacity boost.
Step 5: Review the Matrix The software returns a list of viable compressors. You will see:
Step 6: Generate the Quotation Package The final output is a PDF report containing performance curves, pressure-enthalpy diagrams (P-H charts), and a specific Bill of Materials for the motor flange configuration.
